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'm not entirely sure if I understand you fully mean by that.
What duplicated information under the billing are you trying to send? Unless you just mean that you want the Billing Information itself from PayPal to be sent into your PayPal Account? Or?
Can you please provide us with a link to the jotform you are trying to achieve this on and also explain a little bit more about the workflow you are seeking with this?
We will gladly take a look at this to see if we can help you more with it.
