Login issues with my script.

Hi all.

I am having a bad week. things are not working as they should. Grin. Fix one problem ane another pops up.

I have been successful in logging into other sites using the identity method when a loging pop-up appears. But as yet, I have not been successful in using a loging form that is built into the web page. I believe I am doing this correct.

the purpose of the script is to check for new books and eventually to do searches. Also to learn PWL.

When I use the post approach, I receive the below from the request headers:

loging: 1 
trying to log in

I have removed the actual correct ip addresses and web site for privacy reasons. the code I am using to log in is:

use strict;
use constant DEBUG => 0;
use warnings;
use LWP::UserAgent;
use HTML::TokeParser;
use URI;
use HTML::TreeBuilder 3;

 my $web_page = 'http://www.x.net/c-60-my-books.aspx'; 
my $login_page = 'http://www.x.net/signin.aspx';

 my $browser = LWP::UserAgent->new(  );
# Simulation of browser tag.
#$browser->agent("Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.0.5; .NET CLR 2.0.50727; ffco7) Gecko/2008120122 Firefox/3.0.5");

# create an empty cooky jar.
$browser->cookie_jar( {} );
 my $username_label = "EMail"; # email label. 
 my $password_label = "txtPassword";
 my $user_id = 'name';
 my $password = 'x';

my $response; # stores the response object.

print "trying to log in\n";
$response = $browser->post(
 $login_page,
 [
 $username_label => $user_id,
 $password_label => $password,
 'LoginButton' => 'Login'
 ]);

my $text = $response->status_line( );
print "response: $text \n";
my $headers = $response->headers_as_string( );
print "headers: $headers\n";
my $content = $response->content(  );


Any clues on what is not working, would be welcomed. is it possible to login via the:

$browser->identity ( )

approach?
