What is the file size to upload with dropbox and JotForm?

Hi, I signed up for Jotform and also a pro Dropbox account and linked the two. I made an upload page and went into the settings to a allow up to 1gb files size. I can't get this to work however. Any thoughts? Thanks

To the best of my knowledge, the maximun size to upload in your Premium account is 1GB, however, I do not know if you should have limitations with your dropbox account.

You mentioned above you can not get this to work, can you please be more specific as if any error message is displayed or if it freezes or any other message like "Please wait", maybe you would be able to include a screenshot of the output.
