Thanks for the help, Jason.
As you noted, the form doesn't redirect or send in an email, but it does upload the file to the folder on the server. I also don't want to store the contents in a database, just send in an email.
So I opened the file in the WA UI and re-entered the email settings.
It didn't give me the option to Save the settings when I clicked FINISH...it just updated the file in DW. But it removed the File Upload functionality. I had to remake it.
I edited the UE4 behavior to add the redirect page, saved it and re-uploaded the page.
It is uploading the attachment to the server, but not sending an email or redirecting.
I did save your original file in a different folder, so I still have it. But the form is still not sending or redirecting.
Appreciate your help.
