This should work:

PHP Code:

<?php 
chdir("/path/to/forums/");
require("./global.php");
include("/path/to/header.php"); ?>

<table><tr><td>
sdfsdfsdfsdfsdfsdf
</td></tr></table>

<?=$avatarcustomposts;?>

<table><tr><td>
sdfsdfsdfsdfsdfsdf
</td></tr></table>

<?php include("/path/to/footer.php"); ?>

you must use chdir() (change directory) otherwise you may get include errors with admin/functions.php, and the global.php include must be above your header, otherwise you will get send headers errors.
