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've checked your forms and it is working fine. I was able to open all your forms. Normally, this error appears when the form is disabled or there is a limit applied on the form.
If you need to collect payments from the user, then you need to use one of our payment processors.
Please let us know if there's anything we can help you with. Thank you!
