Global.php variables? (trying to call foruminfo)

[James T Brock]

I'm trying to use this mod on my forums, however I ONLY want it to apply to one specific sub-forum. Currently the mod works by applying this code at the top of the global.php file..

if(file_exists('dnp_fw.php')){require_once('dnp_fw .php');}

How do I make it so that it only calls that script if the user is inside of a specific subforum? Right now I'm trying to use the below code but it's not working, I assume it's because the global.php file doesn't have access to these variables? What do I use instead?

if ($foruminfo[forumid]==XX) {

if(file_exists('dnp_fw.php')){require_once('dnp_fw .php');}

}
