RSS-XML-Javascript Feedback into HTML

[WS|Scorpion]

I tried that earlier today, but it didnt display what I hoped for. How do I make it display the exact section of the forums, and display the latest exact number of posts on a custom html?

<script src="http://www.yourdomain.com/forumpath/external.php?type=js" type="text/javascript"></script>
<script type="text/javascript">
<!--
for (i in threads)
{
document.writeln(threads[i].title + " (" + threads[i].poster + ")<br />");
}
//-->
</script>

Since thats the code I used, which section I should edit for it to display the latest 15 posts in this link?
