How do I get the forms to be submitted to Dropbox?

I have read your instructions over and over and I still don't understand how to integrate with Dropbox. I thought I did it, but there's no folder in my Dropbox account that I thought the integration creates. Here is what I need: I will be creating 7 different competition forms. Each form that is submitted will need to go into a folder that has the name of the form. Each form will also have an mp3 upload of their audition that the applicant will need to upload into. 

How do I get the forms to be submitted to Dropbox, and where will the mp3s be uploaded once the forms are submitted? 

The folder won't be created automatically after the integration. The folder will only be created as soon as you start getting submissions. You may consider testing the form to create the folder, you can delete the submission after.

All forms will have its own folder in your Dropbox account. MP3 files and the submission's PDF will be added to the submission folder in your Dropbox. 

You'll see the check mark in the Dropbox image in the Integrations section once the integration is connected:

I hope that clarifies your question.
