use CGI;
use strict;

my $q = new CGI;
my $called_by   = $q->param('submit');
my $confirmed   = $q->param('confirmed');
my $script_name = "tagbucket_template";

my ($message,$formstuff);

# check how we were called

if ($called_by ne 'submit') {

  # this is the first time the form is displayed

  # get some names from a database

  # assume for now that the database returns an array
  # with something like the following

  my @results = ('red','orange','yellow','green','blue','indigo','violet');

  $formstuff = $q->checkbox_group(-name=>'tagbucket',

} else {

  if ($confirmed ne 'yes') {

    # this is the confirmation page

    my @stuff_to_delete = $q->param('tagbucket');
