Need help with HTML/javascript for external data provider

[TimBrown]

I'm trying to set up my external data provider but nothing shows up with the following code:

<script src="http://forums.x.com/external.php?type=js&forumids=6,12" type="text/javascript"></script>
<script type="text/javascript">
<!--
for (i = 0; i < 12; i++)
{
document.writeln("<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\" style=\"border-collapse: collapse\" width=\"440\" height=\"26\" valign=\"middle\">
                  <tr>
                    <td><b><a href=\"http://forums.x.com/showthread.php?threadid="+threads[i].threadid+" target=\"blank\">"+threads[i].title+"</a></b>&nbsp;<font size=1>- Posted by "+threads[i].poster+" at "+threads[i].threadtime+"</font></td></tr></table><br />");
}
//-->
</script>

If I take out the table part within the document.writeln it works but I need the table part to fit it in with my design, so this must be a HTML/javascript problem. Could someone help me out please?

Thanks
