php code question

Okay phpBB gurus or those that want to give this a shot:

I'm simply trying to get the total online userlist to be displayed on each forum page instead of just on the main index page.  Here is what I've found.  If you use {LOGGED_IN_USER_LIST} on the main index you get a list of the current users online.  The odd thing is, if you use the same {LOGGED_IN_USER_LIST} on the individual forum pages, it is only set to echo the users that are viewing that particular forum.

I think I've tracked the issue down to page_header.php but I don't know enough about php/sql to do what I need to do.  There appears to be code here that determines what {LOGGED_IN_USER_LIST} returns based on what page you use it from.

I've posted the full code of page_header.php as it defines {LOGGED_IN_USER_LIST} and appears to show the code I'm referring to.  

I'd really just like to make {LOGGED_IN_USER_LIST} always return the total users online, regardless of how/where it is used.

I'd greatly appreciate the help.

Here it is:
