I've been thrashing around the monastery (and Google, and a few other programing sites) for a few days trying to figure out why my code for setting a cookie works in one cgi script but not another. This one works (i.e. it sets the cookie):

# Process form and set cookies
   my ($cat) = param('butCat');
   my ($typ) = param('txtTyp');
   my ($to_set) = cookie(-name => 'cat',
      -value => $cat,
      -path => '/',
      );
   my ($to_set_a) = cookie(-name => 'bus_com',
      -value => $typ,
      -path => '/',
      );
   print header(-cookie => [$to_set, $to_set_a]);

This one doesn't (i.e. no cookie):

    $i = 0; 
    while (@record[$i]){
        # Set adv_cookie
        $cgi = CGI->new;
        $adv = @record[$i];

      my ($to_set) = cookie(
          -name => 'adv',
          -value => $adv,
          -path => '/',
      );

print header(-cookie=>[$to_set]);

    $i=$i+1;    
    my (@args) = ($path."advlst.cgi");
     system(@args);

I have checked for the cookie manually on the browser as well as using cookie('adv') in the script called using system. I'm picking that I've done something really simple wrong but I can't for the life of me see how this is different from a dozen or so scripts I have seen online (or from my first script). Any suggestions?
