This code is to show how many are in the chat room on the link like this: Chat(2).
You only need to change inc_header.asp.
Line 40 add the include file so it looks like the one below. Note to change your path if your chat program is somewhere else
<!--#INCLUDE FILE="inc_func_common.asp" -->
<!--#include file="Chat/inc.utilities.asp" -->
Around 526 where you added your link for the chat program change it to look like this
if strDBNTUserName <> "" then
Response.Write " |" & vbNewline & _
" <a href=""javascript:openChat()""><acronym title=""Chat with other users..."">Chat</acronym></a><font color=""#FF0000""> (" & countUsers() & ")</font>" & vbNewline
end if
Thats it
Hope that helps
