I need help getting the ads there

I've created the ad_networks php file, & the txt file and set write permissions for the txt file, then added the code to the footer through the forum's admin panel.

The ads are displaying on some pages (I added the code manually to each of these pages):
http://www.alienhub.com/website/recommend.php
http://www.alienhub.com/website/links.php

But not on the homepage or any forum page. Please help

URL: http://www.alienhub.com/website
Scripting language in use: php
Server: IIS

 

Ads need to show on every page

 

I've added the php code to site footer through the board's admin panel, same way I had added adsense javascript earlier. It's not working however, the code is actually visible when I try to "View source" which shouldn't be as its php.

Check it out:

<?php
	ini_set ("include_path", ini_get ("include_path") . ':../:../../:../../../:../../../../');
	include ('ad_network_455.php');
	echo $ad_network;
?>

Code (markup):
