I was looking for a script which allows a user to upload multiple files and found this. It's exactly what I'm looking for, but it's not working for me. The html form correctly selects the files and uploads them, but my theory is the folders (based on username and email) are not being created properly.
I wonder if something's changed with Google Drive recently which prevents this script from working.
Are you able to test it again and confirm that it still works?

Thanks in advance,
Adit
