I'm having the same problems as everyone else.
I've tried setting the email settings like the image the person before attached to this thread - where it says "submitted file" and I've also tried following the directions on that very setup page where it says to use the enter value field and I chose the first file upload record (it shows several when you go to select a record using the lightning bolt). Both ways do not attach any file to the email.
I bought universal email for this very purpose. I've followed the directions but no attachment gets added.
Can you create a support ticket for me?
