Your page is a huge mess from the point of view of valid code, and you are using some fairly unorthodox layout as well. A quick fix would be to set an explicit height for the body element (addition highlighted):
Code:
<body>
<style type="text/css">
.bottom {color: #ffffff; font-family: tahoma, times, verdana; font-size: 10px; letter-spacing: 2px; text-transform:uppercase; font-weight:bold; text-align:center;}
body {height:2000px;}
</style>
<div style="width: 600px; height: 200px; overflow: auto; position: absolute; top: 0px; left: 280px; padding: 0px;" >
<center>
<script type="text/javascript"><!--
