Well, I don't see anywhere where you are: 
print $cgi->header();

[download]
or the like -- so that would be the first thing I would check out.

To further test things I would run the code at the command line and see what is actually getting printed out. This should illuminate alot. You can run it at the command line by doing.. 

./foo.cgi var1=val1 var2=val2

[download]
where "foo.cgi" is your actual program name; "var1" etc, are each of the variables you are referencing; and "val1" etc, are values to test in those variables.

The script should then run and you will be able to see what is trying to be sent to the browser.. you will like see something strange appear -- and that will likely be your error.
