vb.org Archive - trying to make custom page, getting blank page instead

I'm trying to create a custom page based on this tutorial, but am only getting a blank page as a result. What am I doing wrong here?

script:

Code:

<?php 



// ######################## SET PHP ENVIRONMENT ########################### 

error_reporting(E_ALL & ~E_NOTICE); 



// ##################### DEFINE IMPORTANT CONSTANTS ####################### 

// change the line below to the actual filename without ".php" extention. 

// the reason for using actual filename without extention as a value of this constant is to ensure uniqueness of the value throughout every PHP file of any given vBulletin installation. 



define('THIS_SCRIPT', 'thanks_leaderboard');  



// #################### PRE-CACHE TEMPLATES AND DATA ###################### 

// get special phrase groups 

$phrasegroups = array(); 



// get special data templates from the datastore 

$specialtemplates = array(); 



// pre-cache templates used by all actions 

$globaltemplates = array( 

        // change the lines below to the list of actual templates used in the script 

        'thanks_leaderboard', 

); 



// pre-cache templates used by specific actions 

$actiontemplates = array(); 



// ########################## REQUIRE BACK-END ############################ 

require_once('includes/./global.php'); 



// #################### HARD CODE JAVASCRIPT PATHS ######################## 

$headinclude = str_replace('clientscript', $vbulletin->options['bburl'] . '/clientscript', $headinclude); 



// ######################################################################## 

// ######################### START MAIN SCRIPT ############################ 

// ######################################################################## 



$navbits = array();  

// change the line below to contain whatever you want to show in the navbar (title of your custom page) 

$navbits[$parent] = 'Thanks Leaderboard'; 



$navbits = construct_navbits($navbits); 

eval('$navbar = "' . fetch_template('navbar') . '";'); 



// change the line below to contain the name of the actual main output template used in your script 

eval('print_output("' . fetch_template('thanks_leaderboard') . '");'); 





?>

template:

Code:

$stylevar[htmldoctype]

<html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">

<head>

$headinclude

<title>$vboptions[bbtitle]</title>

</head>

<body>



$header

$navbar



<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" 



align="center">

<tr>

<td class="tcat">Thanks Leaderboard</td>

</tr>

<tr>

<td class="alt1">Other Bluff...</td>

</tr>

</table>



$footer

</body>
