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.
Since you are on the Free plan you only have 10 payment submissions. To have more payment submissions, you can either wait the first of next month for another 10, or upgrade to have 1000+ payment submissions - Pricing Page.
You can also get a few submissions for free by clicking some simple URL but, I'm not sure if they include payment submissions as well. To do that, go to Account > Get More and choose the option you want.
