Hi,

Im using WWW::Mechanize for screen scraping. The script will ocate the login form on the pages im visiting, and log on with credenticals. This works well, but after a time it crashes with the error:

Can't call method "value" on an undefined value at /usr/local/share/perl/5.8.8/WWW/Mechanize.pm line 1376.

I have a strong suspicion that this is based on the fact that mechanize did not find the textbox "username" on the site in question, for some reason. Maybe the site was down for a couple of seconds.

How should I do error handling on this? To ensure that the errors are logged, but the script does not stop ?

Here is some code to explaint what im doing

my $mech = WWW::Mechanize->new( agent =>$browser_agent);
$mech->cookie_jar(HTTP::Cookies->new());


$mech->get($url_login);
$mech->form_number($form_nummer);
$mech->field('username' => $username);
$mech->field('password' => $password);

$mech->click();  <--- I think this is where the error gets trown, if t
+he "username" textbox is not present
