I'm having some difficulty getting my carousel and the underlying placeholder to align correctly. Any suggestions? The carousel can be viewed at this site.
http://eteamz.active.com/LPXTREME14U/news/

Following is the script inserted in the site. Can anyone tell me where I went wrong? Also I would like to center the carousel on the page.
<body onload="Carousel()">
<script type="text/javascript">
