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.
I understand that you want to title the filename in the DropBox folder with the text entered in one of the fields from your JotForm. You may select the field from the list to list as a sub-folder and the PDF created shall also be having the same field value.
Please see the recorded session below with the form integrated with DropBox using FullName field and Submission ID.
Hope this information helps!
