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.
Sorry but what you are trying to achieve is not possible with Jotform.
You may consider using WebMerge instead which I think might help but since we do not have integration with this, you may create custom script and enable Post Data to achieve what you want. http://www.webmerge.me/
Let us know if we can be of further assistance.
