I need the default code to correct this..

[Champster]

I'm getting a "Done but with errors" prompt at the bottom of the browser on my forum because of a hack I installed.

The error code I am getting is:

Line: 172
Char: 4
Error: 'IMGDIR_MISC' is undefined
Code: 0

This problem started when I entered a hack for "Fading over link" code as seen here. http://www.vbhackers.com/forum/showthread.php?t=3640

PHP Code:

<script type="text/javascript"src="fader.js">
<!--
var SESSIONURL = "$session[sessionurl_js]";
var IMGDIR_MISC = "$stylevar[imgdir_misc]";
var vb_disable_ajax = parseInt("$vboptions[disable_ajax]", 10);
// -->
</script> 

Thanks for your assistance.
