How Would I pull Information From vBulletin?

[Pc 1203]

I just get a blank page. Here is my code:

<?php
chdir('/home/penguink/public_html/forums');
require_once('/home/penguink/public_html/forums/global.php');

// Add the usual require stuff here
$wanted_userid = 9; // The user id of the user you want the data from 
$userinfo = fetch_userinfo($wanted_userid);

$posts = $userinfo['posts'];
// $joindate = $userinfo['joindate']; // Unformatted
$joindate = vbdate($userinfo['joindate']); // Formatted date e.g. Mon 29th Aug 

$joindate
?>

EDIT: Stupid Me! I forgot to use the print command. It works! Thanks Alot! Do you know how to get custom profile fields, though?

EDIT2: When I look at join date I get "1177448760" for my user....
