UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Undef, If, and a couple others

Say I have this code, test.cgi:

#!/usr/bin/perl

print "Content-type:text/htmlnn";

undef ($test);

if ($test eq 'test') {
print 'Did It Work';
}

If I were to type http://www.myserver.com/cgi-bin/test.cgi?test=test

Shouldn't it print "Did It Work" on my screen?

For me all it does is print a blank screen. What am I doing wrong?
