I wonder why variable '$url' and '$url_desc' won't pass information into my hash ('%url_dep'). I'd like to make a hash list with information that are stored in the variables. 
use HTML::TokeParser;
use WWW::Mechanize;
use Data::Dumper;
my $mech = WWW::Mechanize->new();
my $html;
my $url = "http://ug.cal.dal.ca/";
my %url_dep;

start();

sub start{
    $mech->get($url);
    $html=$mech->content();

    my $stream = HTML::TokeParser->new(\$html);
    
    while(my $token = $stream->get_token()){
    if($token->[1] eq "div" && $token->[2]{id} eq "content-zone5"){
        while(my $token = $stream->get_token("a")){    
                my $url_desc = $stream->get_phrase();
                my $url = $token->[2]{href};    
                $url_dep { $url } = $url_desc;
            }
        }
    }
    print Dumper \%url_dep;
    
    foreach (sort { $a <=> $b } keys(%url_dep) ){
        my $dep_url = $a;
        my $dep_name = $b;
        print $dep_url;
        }
}
