This is an Über simple response limiter for Google Forms that only accounts for number of responses in a Google Form.
- Click on the three vertical dots and open the Script editor
- Copy-Paste
Code.gs
andSidebar.html
into your editor & save the changes; you can rename the project (top left, whichever way you want, e.g. "Form response limiter") - Back in your Form edit view, refresh the page (you should see a new icon appear left of the "customize theme" icon, which is called "Add-ons")
- Click on the "Add-ons" icon and then select your newly created script. Google will ask you to grant the script permissions. You'll need to allow these.
- Click "Install" and then "Configure response limiter"
- A side-bar will appear, called "Form limiter
- Check "Limit form responses" and then select the max number.
When the number of responses hits the limit set in step 7, the script will auto-close the Form.
