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.
If no payment have been received then there's a possibility that the person who submitted the form didn't settle the payment right after getting redirected to the Paypal Payment page which resulted to incomplete payment submission. Here's how you can check incomplete payments:
Or maybe there's a problem in your form or the configuration causing people unable to submit the form. If you can share us the form, we would be happy to check it further.
