I understand to send data to another page, you use:

print start_form(
    -action=>'results.cgi');
    various form stuff....
print end_form;

I would like to be able to take the selected options from popup_menu's as well as a textbox to return information from a database. So I'm going from a search page to a results page. The search page is displaying information from the database, then whatever the user picks as their selection in the popup_menu gets passed to the results page to query the database.

use DBI;
use CGI::Cookie;
use CGI qw /:standard/;
use warnings;

#checking if cookie is set, if not redirecting to login
my %cookies = CGI::Cookie->fetch;
if (! defined $cookies{'authorized'})
{
        print redirect('login.cgi')
}

#connecting to DB
my $dbh = DBI->connect("dbi:SQLite:dbname=/path/to/database.db","","")
+;

# getting artist info
my $sth = $dbh->prepare('select artistid, name from artist');
$sth->execute;

# getting genre info
my $sth2 = $dbh->prepare('select genreid, name from genre');
$sth2->execute;


#printing header
print header,
start_html('Database Search'),
h2('Select items from the dropdown menus to help filter your results.'
+),
br,br,
end_html;

print start_form(-action=>'results.cgi');
end_form;     ### THIS CAUSES REDIRECT TO RESULTS WHEN USER HITS SUBMI

When I go to print the parameters ($userArtist, $userGenre, $trackName), only trackname gets printed and I don't see anything for artist or genre. I am not able to find anything online about this, or maybe I'm just unsure how it works, any help is appreciated.
