Custom chatbox error

Hello, i want to add a custom chatbox to my forum. I made a CHAT ROOM forum where there will be many chatrooms to reduce load. But, when i add the HTML code in a new topic, it doesn't come (only the codes show up!). I tried to press the a/A button, but i can see the chatbox only in the message field, but when i SEND it, it doesn't show up. Below is the HTML CODE for chatbox:

Code:

<script type="text/javascript" language="JavaScript">
document.writeln('<iframe src="http://www.spinchat.com/cb/start?chn=Gaming%20Debates%20Chatroom;srv=1;cat=3;id=AL9FtyNl4RGREPN34-3XMA;st=1;w=640;h=480;url='+escape(location)+'" width="640" height="480" border="0" frameborder="0"></iframe>');
</script><noscript>

</iframe></noscript><br>Get your own chat on spinchat.com!

Help will be appreciated

Why are you adding it to a topic? Add it to a widget or announcement.

I've made different chatzones, like general discusison chat, gaming chat, ps chat .. .so thats the reason :d

You could make a few different html pages (for each of your chatzone one) and put the script in there. Then add each HTML page into the navigation bar.

Just a suggestion...

I want to add them in topics, not navigation bar... visit my forum at http://www.gamingdebates.co.cc then go to CHAT ZONE ... i want to make topics there and add chatboxes there

Depends if javascript works inside posts?
And EVEN if it does, document.write might not.
