I have logged into my adsl modem using the following code. 

use strict;
use WWW::Mechanize;
use LWP::Simple;
use MIME::Base64;

my $pubIP = get("http://whatismyip.org/");
my $url = "http://$pubIP/resetrouter.html";

my $username = "foo";
my $password = "bar";
my $button = "Save/Reboot";

my @args = (
    Authorization => "Basic " .
        MIME::Base64::encode( $username . ':' . $password )
);

my $mech = WWW::Mechanize->new(autocheck => 1);

$mech->credentials( $url, "test", $username, $password );
$mech->get( $url, @args ) or die $mech->die;
print $mech->content;
$mech->click($button);

the return value of print $mech->content; is as follows which means i have successfully logged into my adsl modem: 

<html>
   <head>
      <meta HTTP-EQUIV='Pragma' CONTENT='no-cache'>
      <link rel="stylesheet" href='stylemain.css' type='text/css'>

function btnReset() {
   var code = 'location="rebootinfo.cgi"';
   eval(code);
}

function frmLoad() {
   var sysReboot = '0';
   var lanRefresh = '0';

   if ( sysReboot == '1' )
      btnReset();
   else if ( lanRefresh == '1' ) {
      var code = 'location="resetrouter.cgi?lanRefresh=0"';
      eval(code);
   }
}

// done hiding -->

   </head>

but immediately after print statement, as i pass through the $mech->click($button) statement i am getting the error Can't call method "click" on an undefined value at c:/Perl/site/lib/WWW/Mechanize.pm line 707.

did lot of googling and searching perl monk as well...got the results as saying the object is not initiated...in my case $mech....but i can't see how.

Please suggest me where am i doing it wrong.
