Ok here is how I do a forum chooser.

First create the option, and in the field, Option Code add the following:

"; $forums = array(0 => $vbphrase['none']);
if (is_array($vbulletin->forumcache))
{
  foreach($vbulletin->forumcache AS $forumid => $forum)
  {
  $forums["$forum[forumid]"] = construct_depth_mark($forum['depth'], '--') . ' ' . $forum['title'];
  }
}
$right = "<select name=\"setting[$setting[varname]][]\" id=\"".$setting[varname]."\" tabindex=\"1\" class=\"bginput\" size=\"20\" style=\"width:300px;\" multiple=\"multiple\">\n";
$right .= construct_select_options($forums, explode(',',$vbulletin->options[$setting[varname]]), false);
$right .= "</select>\n"; $null = "

Then you will need to do the plugin for admin_options_processing

    $setforums = 'VARNAME FOR YOUR SETTING';
    if ($oldsetting['varname'] == $setforums)
    {
       if (in_array(0, $settings[$setforums]))
       {
          $settings[$setforums] = '0';
       }
       else
       {
           $settings[$setforums] = implode(',',$settings[$setforums]);
       }
    }
    $setforums = '';

Then you can use the code I provided earlier.
