[MeLoNiSyUmMy]

so i changed my layout on my icon site www.xanga.com/iCON___LOVExx3and my automatic scrollbar isnt working. it worked before on an older layout but once i had changed the layout, it just stopped working.

here the code i used..
(custom header)

<!-- begin code provided by createblog.com --><br /><!-- begin code provided by createblog.com --><br /><style type="text/css"><br />.custom{<br />width: 200px; <br />height: 200px; <br />z-index:100; <br />overflow: auto; <br />border: px #000000 solid; <br />background: #ffffff; <br />}</style><br /><!-- end code provided by createblog.com --><br /><!-- end code provided by createblog.com -->

(website stats)

<!-- begin code provided by createblog.com --><br /><!-- begin code provided by createblog.com --><br /><script><br />var tds = document.getElementsByTagName ('a');<br />for (var i = 0; i < tds.length; i++) {<br />timeString = tds[i].innerText;<br />if(timeString.match(/\d+:\d+ [ap]m\b/i)){<br />if(!tds[i].parentNode.parentNode.parentNode.parentNode.parentNode.tagName.match(/table/i)){break;}<br /> table = tds[i].parentNode.parentNode.parentNode.parentNode.parentNode;<br />stuff = tds[i].parentNode.parentNode.parentNode.previousSibling.lastChild;<br />inner = stuff.innerHTML<br />stuff.innerHTML="";<br />stuff.insertAdjacentHTML('afterBegin','<div class="custom">'+inner+'</div>');<br /> <br />}<br />}<br /></script><br /><!-- end code provided by createblog.com --><br /><!-- end code provided by createblog.com -->

is it because of my layout?
