Thanks for responding! Yes, Matt's FormMail. (It was already installed by my host, so I didn't look any further.)
My problem is that I don't know how to add that extra value to the Subject line. I've tried all sorts of things and nothing seems to work. I get "Business Contact", but when I do get the "last_name" variable, it's just like that. It's not the sender's actual last name.
If I try putting it on a second line, "Business Contact" is replaced by "last_name".
I tried separating them, but on the same line, like: (input type=hidden name="subject" value1="Business Contact" value2="last_name")
My editor program liked that one, but the only part that showed up in the sent email was "Business Contact".
Separating the two with a comma, I do get both items, but no matter what, I can't get the actual person's last name.
Is there a good, EASY tutorial somewhere for using FormMail, with lots of variable info?
