in reply to A Beginner Apparently Sucks With Hashes...

I can tell you why it happens... this line right here:

%FormData = split(/=/, $Part);

[download]

Inside that foreach loop, you're overwriting the hash each time. You'll probably want to do something like this:

my ($name, $value) = split /=/, $Part;
$FormData{$name} = $value;

However... there are MUCH easier ways to do parameter grabbing, and I (along with 99% of the monastery) suggest you check out and use CGI.pm, along with strict and -w, if you aren't already. Hope that helps!

Update: Added example code.

    Following CheeseLord's advice might lead to something like:

    #!/usr/bin/perl -w

use strict;
use diagnostics;
use CGI qw/:standard Vars/;
use CGI::Carp 'fatalsToBrowser';

my @page;

my %form_data = Vars;
foreach my $input_name (keys %form_data) {
    push @page, p( {-align => 'center'},
                   b($input_name),
                   ": $form_data{$input_name}" );
}

print header, html(@page);
