JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
The easiest way to accomplish this it to add an edit link to your autoresponder:
This will allow your users to return to their filled out form at any time and update their submission.
If you have any further questions, let us know and we will be happy to help.
