Personally I would recommend using CGI.pm, but let's say you have a really good reason for not using it there are a few things to look at to maybe help you along the way...

You are sending information from your form via POST and GET methods. Normally this will not work, so at least a portion of your information is being ignored, which could be your whole problem.

You don't describe how you are retrieving your data, but I would look into these two variables:

$ENV{'CONTENT_LENGTH'}    #normally used with POST method
$ENV{'QUERY_STRING'}      #normally used with GET method

to see where your information is and how it is being delivered.

But I would use CGI.pm ( you might also want to give -w and use strict a spin as well).
