What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
We do not have a record of attempted submissions, only completed ones. If the users were presented with the thank you page, their submission should have been recorded. If there was a connection issue or something of that nature when the form was submitted, the entry may not have been complete. I do not believe there has been anything recently on our end that would have prevented users from completing your form. The form itself looks to be fully functional.
