I created a form with the File Upload control. Our users have Visitor permissions which have been modified to allow adding new list and document library items. However, when they submit, they are receiving an "Unable to upload files." error. What are the minimum SharePoint permissions required for a user to upload a file to the form? I tried to change it to Contribute but that didn't work either.
