Is this your entire script? I can't see you initializing $formdata anywhere, so there is nothing stored in it. try putting use strict at the top of your script, well as the second line.
You need to use something to collect the data from your form. Everyone around here recommends cgi.pm
Here is a quick example. The documentation is included with the standard perl distribution.
use strict;
use cgi;

my $query = new CGI;

my $email = $query->param('email');

You can then go onto use the value of $email in your script. It should contain the data in the field named "email" when submitted to your script. Repeat for all paramaters you are interested in. Hope this helps.

Update: I obviously spent too long typing this... seems b10m bet me to most of the info.
