PerlSufi has asked for the wisdom of the Perl Monks concerning the following question:

hello monks, I wanted to check if a config file param is not "" and if it isn't, crawl with the information contained in the param. Here is what I have:
use WWW::Mechanize; use Config::Simple; if($cfg->param("$ARGV[0]".".notification2") != "") { my $notif2 = $cfg->param("$ARGV[0]".".notification2"); $mech->get('http://path/to/site.php'); $mech->submit_form( form_name => 'notification_form', fields => {"email" => $notif2, } ); }

That param is not empty, so why is it not posting?
Thanks in advance

    != compares numbers whereas ne compares strings. warnings usually picks this up. HTH.

      That did it..
