scroll bar in blogrings..., is it possible? Options

[mezzanine]

does anyone know if it's possible to add a scroll bar to your blogrings?... i was wondering if there's a way to alter this code so it would work for the blogring module...

CODE

<!-- begin code provided by createblog.com -->
<script type="text/javascript">
// original by EasterEgg, xanga.com/easteregg
// modified to reflect xanga's current html schemas
function adjustSirListHeight()
{
   // *** define the height of your SIR-list in the line below
   var sirListHeight = '90px';
   var allTables = document.getElementsByTagName('tbody');
   for (i=0; i < allTables.length; i++)
   {
       if ((allTables[i].innerHTML.indexOf('Sites I Read') != -1) &&
           (allTables[i].innerHTML.toUpperCase().indexOf('<TABLE') == -1))
       {
           sirlist = allTables[i].lastChild;
           temp = sirlist.firstChild.innerHTML;
           sirlist.removeChild(sirlist.firstChild);
           td = document.createElement('td');
           div = document.createElement('div');
           div.style.width = '190px';
           div.style.height = sirListHeight;
           div.style.overflow = 'auto';
           div.innerHTML = temp;
           td.appendChild(div);
           sirlist.appendChild(td);
           break;
       }
   }
}
if (navigator.userAgent.indexOf('Mac') == -1)
   if ((document.URL.indexOf('weblogs') == -1) &&
       (document.URL.indexOf('guestbook') == -1) &&
       (document.URL.indexOf('events') == -1) &&
       (document.URL.indexOf('reviews') == -1))
       adjustSirListHeight();
</script>
