I'm trying to get a little more familiar with the WWW::Mechanize module and have the following situation...I'm able to get a specific URL, but I'm trying to click a link on the page that uses javascript behind the scenes and two hidden fields. I'm able to get the required data for the two hidden fields but cannot submit the form for some reason. Can anyone tell me what I'm doing wrong? This is the script I'm using

use strict;
use warnings;

use WWW::Mechanize;
use Data::Dumper;

my $mech = WWW::Mechanize->new();

my $url = 'http://myspace.com/Modules/ViewFriends/FriendsView.aspx?%3f
+fuseacion=user.viewfriends&friendID=' . 16193600;
$mech->get( $url );

#print $mech->content();
# my $links = $mech->find_all_links();
# print Dumper($links);

my $next_link = $mech->find_link( text_regex => qr/Next/i );
if($next_link) {
    
my $url = $next_link->url();
if($url =~ /javascript:__doPostBack\('(.*)','(.*)'\)/) {
    
    my $target = $1;
    print "TARGET: $target\n";
    my $argument = $2;
    print "ARGUMENT: $argument\n";

    $mech->submit_form( {
    form_name => 'aspnetForm',
    fields_ref => {
            '__EVENTTARGET' => $target,
            '__EVENTARGUMENT' => $argument,
                      },
     } ) }
} 
else {
    print "no more links on page\n";
}
