Parse Custom BBcode on External Pages

[Cadellin]

I suspect there maybe a solution somewhere for this but after a day of searching and failed attempts I felt it was time to ask.

This is the code I'm using at the moment:

if (!is_object($bbcode_parser)) 
    { 
    require_once(DIR . '/includes/class_bbcode.php'); 
    $bbcode_parser =& new vB_BbCodeParser($GLOBALS['vbulletin'], fetch_tag_list(),true);
    } 
    $taskdesc = strip_tags($taskdesc);
    $taskdesc = $bbcode_parser->parse($taskdesc,0,true);

Which works fine for the default BBcode but I can't get any custom code to work.

If someone could point out where I'm going wrong I'd really appreciate it as this is doing my head in!

Cheers
