Thanks so much for your help. I wish it was easy to compile all the fixes, methods, and nuances that we get from the support forums and put them in the extension documentation. So am I correct (for future knowledge) that UE4 will automatically attach files to emails (assuming the form was correct to begin with of course) but applying the file upload behavior routes the file to the server instead of attaching it to the email? I guess I expected it to do both...but it works for this situation as it is, just want to know future options...
