display script code in navgiation tab

[Chadi]

I'd like to display total number of users in chat. The code is below.

<script language="javascript" src="somepath/connections.php"></script>

I want to display it (float right) in the chat tab. The chat tab is created using the default navigation manger.

See www.talkjesus.com

So it says "chat" in the green tab", I want the displayed total users displayed on the right of it like this

chad (space in middle) 10

10 = example of number of users in chat.

My question now, how can I integrate that script code so it displays in the tab specifically? I'm using amend tabid to URL too. The ID is

#tab_oda5_837


Thanks!
