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.
If I understand your concern correctly, you have integrated your form to Dropbox, however, the PDF file for the submission is not being sent to your Dropbox? I tried to integrate one of my forms to Drop Box but I was not able to replicate the issue you are reporting. Can you try to reintegrate (remove integration and integrate again) you form to Dropbox and see if it will work now?
We will wait for your response.
