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.
I checked your account and I notice that there is only one form there. The form "Untitled Form" appears to be empty. Do you have the missing form embedded in a website? If yes, then you can provide us with the URL of the website so we can check further. If you accidentally deleted the form, then you may be able to recover it by following this guide: How to Restore Deleted Forms?.
Do let us know how it goes.
