it gives an error global symbol $userid requires explicit package name

Perhaps this is because you use strict and these variables are not declared?
Sorry if my advice was wrong.

I put strict off and it gives no errors, then i ran it and it gave line 6 unknown agent 'firefox' and line 1900 of mechanize.pm says there is no form numbered 2, How can i resolve the first error and where does it say the form of html? sorry I am slow in this but I appreciate your help very much:)

my $mech = WWW::Mechanize->new();
$mech->agent_alias( 'Firefox' );
$userid  = "usr";
$password = "password";
$mech->get( "https://login.binck.nl/klanten/Login.aspx?ReturnUrl=%2fkl
+anten%2fdefault.aspx" );
$mech->submit_form(
    form_number => 2,
    fields => {
        userid => "$userid",
        password => "$password"
    },
    button => "btnSignon"
);
