My Live Support Script

IT also has almost all of the features I want. It uses a microsoft access 2000 database (I use the following code to connect to the database:

DSNtemp="DRIVER={Microsoft Access Driver (*.mdb)}; "
DSNtemp=dsntemp & "DBQ=" & server.mappath("SOMEPLACE")
sqlstmt = "Select * From TABLENAME"
Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open sqlstmt, DSNtemp, 3, 3
Do until rs.EOF or rs.EOF)

The code works fine, I would just like to add a thing and it would tell what page the user(s) are/is at and then I can request a chat with them and a box would pop up asking them if they would like to chat. My oly problem is how would I keep track of the visitors on my site, and how would I know when they left the site?
