i have also different prolem. when i fill form like here: $mech->field('username' => 'test'); everythig goes ok, but when i fill it with some var: $mech->field('username' => $test); i should tell that var $test is passed as an sub arg. It tells me error: Died at /usr/local/lib/perl5/site_perl/5.8.8/WWW/Mechanize.pm line 1681. Any ideas? best gegards, rafael
