I use this on a regular html file, with this line on top of any html file outside of vbulletin:

<?php
chdir("/home/weebie/public_html/community/");
include("./topstory.php");
?>

Now, I've decide to use vbindex and place my index.html into the vbulletin template. How do I still be able to use the commands that I have above inside a template, such as //$post['image'] etc..? How do I include all this, please help....
