"X people currently in Chat" on forumhome

[KimG]

Hi,
I am trying to diplay the total number of people who are in my chat room on the forumhome, beneath the currently online bar.

Currently I have the chatroom setup with a refreshing chat.php in an iframe to return the result that the user is in the room.

Therefore on my "whose online" page users in chat are displayed as entering chat!

Now how do I get vbulletin to count up the number of people who = "chat" in "whose online" and then display this number on the forumhome (which consists of both members and guests)? And furthermore display their names, if they are members.

Is there a simple way?
Thanks
Kim
