HTML formatting in document.write

[timcoweb]

I have the following script from my phpadsnew banner manager. I have text ads linked to my site and would like to format my text. Here is my script:

<script language='JavaScript' type='text/javascript' src='http://timcoweb.com/phpadsnew/adx.js'></script>
<script language='JavaScript' type='text/javascript'>
<!--
if (!document.phpAds_used) document.phpAds_used = ',';
phpAds_random = new String (Math.random()); phpAds_random = phpAds_random.substring(2,11);

document.write ("<" + "script language='JavaScript' type='text/javascript' src='");
document.write ("http://timcoweb.com/phpadsnew/adjs.php?n=" + phpAds_random);
document.write ("&amp;clientid=6&amp;target=_blank");
document.write ("&amp;exclude=" + document.phpAds_used);
if (document.referrer)
document.write ("&amp;referer=" + escape(document.referrer));
document.write ("'><" + "/script>");
//-->
</script><noscript><a href='http://timcoweb.com/phpadsnew/adclick.php?n=a82656c0' target='_blank'><img src='http://timcoweb.com/phpadsnew/adview.php?clientid=6&amp;n=a82656c0' border='0' alt=''></a></noscript>

Have tried several options and cannot seem to find the righ one. Would like to set the font size, bold and center with html elements.

That's because there's nothing in what you posted that would allow any formatting. Perhaps there is in the remoted .js file, but not here.
