It distinctly says 'Universal email 5' on the behaviors listing, so that's what I assumed.
The 'Send Email Settings' is greyed out when I build a new form. By the way it's specifically a 'Website Designers' form even though I said 'Contact'. But even when I try to build a contact form, the Form Function 'Send Email Settings' is greyed out.
I pasted what the code you sent and it does it but, of course, it's not formatted properly. So I was just trying to recreate a form and apply the Send Email Settings but for some reason they're greyed out.
