Hi,

I am trying to set a cookie at the signup page to register where a user comes from but there must be a mistake in my way of trying it.
Modification to Login.pm:

Code:
 ...  
elsif ($input->{signup_form}) { 
     my $ref = $IN->param('ref') || $IN->cookie($CFG->{user_cookie_prefix}.'ref') || "noref"; 
     my $ref_cookie = $IN->cookie( 
            -name => $CFG->{user_cookie_prefix}.'ref', 
            -value => $ref, 
            -path => '/', 
            -domain => $CFG->{user_cookie_domain} 
        ); 
         print $IN->header(-force => 1, -cookie => [$ref_cookie] ); 
        print Links::SiteHTML::display ('signup_form', 
{  
   Username => $IN->param('Username') || '', 
   Password => '', 
   Email => $IN->param('Email') || '',  
   refID => "$ref",  
   main_title_loop => Links::Build::build('title', Links::language('LINKS_SIGNUP'),  
   "$CFG->{db_cgi_url}/user.cgi?signup_form=1") });

Does anyone have an idea what I am doing wrong.

Thanks
