Aha! I had $email, when I needed $email_address. All I needed was another look...thanks, Phranque.
Now I just need to be able to receive an email letting me know that form data has been submitted...I don't need to have the file that was uploaded actually emailed to me (most files uploaded via this particular form will probably be too large for email anyway), but I do need to receive an email notification that a file has been uploaded. I found info about Formmail.pl, but that seems to be pretty involved...is there a simpler way to get an email sent to me that just tells me someone has uploaded something via my CGI script?
Also, I see the file I uploaded as a test in my "upload" folder on the server, but where is the rest of the form data (name, email address, etc)? I don't see that in the upload folder at all...
Thanks again for the help!
