weird problem w/ query

[harmor19]

Here is a small portion of the form. As you can see "planid" has a value.

<form action="hosting.php?do=do_request" method="post">
<input type="hidden" name="userid" value="1" />
<input type="hidden" name="planid" value="6" />

For some reason the query isn't picking up the value.

PHP Code:

if($_REQUEST['do'] == "do_request")
{

$vbulletin->input->clean_array_gpc('p', array(
    'userid' => TYPE_INT,
    'planid' => TYPE_UINT,
    'subdomain' => TYPE_STR,
    'susername' => TYPE_STR,
    'ignore' => TYPE_INT,
    ));

$getplans = $db->query_first("SELECT posts,title FROM " . TABLE_PREFIX . "hosting_plans WHERE planid='".$db->escape_string($vbulletin->GPC['planid'])."'");
    $hp = $db->fetch_array($getplans);
    
    echo "Plan: ".$hp['title']."<br />Posts: ".$hp['posts'];

} 


When I echo the values it doesn't show the values.
