General Advice

If the addon does not work as intended, the following options often solve the issue:

  1. Create a new Google Forms / Sheets / Docs / Slides document and start from scratch
    • Why could this solve the problem? Many users install multiple addons to test them. Each addon changes settings or changes the document itself, these changes could interfere with our addons.
  2. Use Chrome as your browser
    • Why could this solve the problem? Google products and services (and therefore also Google addons) work best within the Google Chrome browser.
  3. Try the incognito mode
    • Why could this solve the problem? Many users have installed browser plugins (e.g. ad blocker). These plugins are usually not active within incognito mode. If your plugins are also active within incognito mode, please deactivate them. If the addon works within incognito mode, it means that one of the browser plugins is causing the issue.
  4. Update Chrome to the latest version
    • Why could this solve the problem? Usually Chrome should update itself automatically, nevertheless there are situations in which this process is disturbed. In these cases Chrome shows a red "Update" message in the right top corner. Using the latest version of Chrome guarantees having the latest features and bug fixes.
  5. Try a Gmail account ([email protected]) instead of your work account
    • Why could this solve the problem? Your Google Workspace admin might have restricted specific features for your company's users.

Purchase

All licences which can be bought through the checkout have a user scope. As an example: if a licence is bought for "[email protected]", the PRO features will only be available for this single user.
The most frequent cause for this issue is that a different email address was used for purchase than for working with the addon. In this case, please contact us via the contact form and we will make a licence transfer.
If more than 5 licences are purchased at once, discounts are granted. Please contact us via the contact form.
Yes, please contact us via the contact form.
This happens when your bank or credit card has charged additional costs on top from you. Please contact these organisations for more details.
Please contact us via the contact form.
After each successful purchase an email containing the invoice is sent out. At the bottom of this email a link to our payment provider can be found to manage subscriptions and billing details.

Addon - Gantt Chart Project Management

The fix of this bug is out of our control. Just reload the page or wait a couple of seconds more, then all menu items will show up.
The fix of this bug is out of our control. The cause for this error message is that multiple users are logged in within the browser. Just log out with all users, except the one which will be used to work with the addon. Alternatively you can use a different browser or the incognito mode.

  • Editing within the "Editable User Area" (dark-grey border)
  • Button functionalities within the sidebar
  • Edit outside the "Editable User Area" (dark-grey border)
  • Manually copy / paste / delete / insert entire rows
  • Manually copy / paste / delete / insert entire columns
Performing one or more of these actions might break the sheet. Use the buttons within the sidebar instead.
Please watch the following YouTube video to get an introduction to the addon.
The most frequent cause for this behaviour is the use of not supported actions (see section above). The easiest way is to delete the Gantt sheet and create a new one via: Add-ons > Gantt Chart | Project Management | Task Planning > Create Gantt Chart. If the Gantt sheet does already contain a lot of task and you do not want to start from scratch, please watch the following YouTube video to get instructions on how to repair a broken sheet.
The progress bar uses a "conditional format rule", which displays the progress from "0% / dark red" up to "100% / dark green".
Other collaborators also need to have the PRO licence to be able to edit the Gantt sheet.
The start date can not be changed after creation, only the view start can be changed within the addon's sidebar. You have two options: 1) delete your current sheet, create a new one and choose the correct start date 2) create a new spreadsheet and create a new gantt sheet within it.
The numbers are week numbers, the letter "S" or "M" stands for "Sunday" or "Monday" which indicates the first day of the week depending on your country seetings.

The addon limits responses per choice. IT DOES NOT LIMIT responses per question, respones per form or responses per user. Please be informed that Google Forms offerst the ability to limit the form to 1 response per logged in user (Settings tab > Responses > Limit to 1 response).
The following JavaScript logic is used to generate the regex pattern: (new RegExp("***your inserted regex value***")).source This means, that "double escaping" needs to be used. For example: If you would like to use the "any digit token" / "d" you need to insert "\d".
Limits set by the addon are not copied. You need to set the limits again within the new form.
Unfortunately it is currently technically not possible to restore images, therefore only the "text-value" of choices is restored.
All limit rules have an OR-relationsip between each other. For instance: if a question has an active number- and value-limit, the question will be limited as soon as ONE of the two limits is fulfilled.
Within the slower submission a choise has been chosen which does not exist anymore. In this case the response will be categorized as "Question left blank". The form owner can identify such situations within the "Responses tab".
This message is displayed when one or both of the following situations occur:

1) The limit of an already removed choice was increased. In this case the corresponding choice needs to be manually re-added to the question.


2) The limit of an active choice was set equal or below the number of responses. In this case the corresponding choice needs to be manually removed from the question
You should have received an email notifying you about this situation. This situation occurs, if a new choice was manually added to a question, where an individual number limit is active. As a fallback, the limit of 1 was applied for each newly found choice. Please open the addon's sidebar to change these limits as appropriate. Please note, that the red highlighting will disappear as soon as all choices have reached their number limit or due to clicking the "Reset" button.
It is not recommended to activate this setting when using our addon. The user can only see the remaining choices and not all initially available ones. If the user edits his/her response, both form submissions will be counted towards the corresponding choice limit.

The faster submission has deactivated the form. In this case the slower submission will not be recorded in any way. The survey participant can identify such situations with the help of the following warning: "The form xxx is no longer accepting responses. Try contacting the owner of the form if you think this is a mistake."
Within Google Forms click on the "Responses" tab. If the form is active, deadctivate the form with the help of the switch button, then an input field called "Message for respondents" will be displayed where the message can be adjusted. Activate the form again if needed.
Google has implemented a daily quota for sending emails via addons. These quotas depend on the type of Google account used: gmail.com users: 100 mails/day, Google Workspace users: 1,500 mails / day. More information can be found within the "Email recipients per day" section under the following link. If you want to increase the daily mail quota, you need to upgrade to a Google Workspace account.

Please be informed, that these features are only available to PRO users. First of all a new Google Slides document needs to be created. The document can than be customized to the own CI. To include merge tags, just create text boxes and put the corresponding merge tag into it, e.g. {{Name}}. Last but not least the Google Slides document needs to be selected as template within the addon settings. Optionally: New questions can be added to Google Forms and the title of the newly added questions can be adjusted to be a custom merge tag, e.g. {{Department}}. Afterwards the same merge tag can be used within the mail subject, mail contant and custom certificate template. The following YouTube video shows the needed steps.
The following YouTube video shows the needed steps to use custom certificates and custom {{Merge Tags}}. If you have followed these steps and still having issues, please check the following two common mistakes: 1) {{Merge Tags}} are case sensitive, please make sure to always use the exact same term; 2) the same user/Google account needs to have edit access to the Google Forms and the Google Slides document.
