How can I limit the number of forms completed

To my understanding, you would like to set a limit to the number of submissions that your form can only accept. If that is the case, you can set the form to be disabled after a specific number of submission. For information on how you can do that with your form, please check the instructions found in this guide — How-to-Limit-Submissions-in-a-Form

If you have other questions or concerns, please do not hesitate to let us know.
