Well the code in the header of each page is different. In the one that's not working you have the link to the style sheet AFTER the internal styles so anything in there will get overridden.
Also the working page has
body{background-color:#000066;
scrollbar-face-color:#FF0000;
scrollbar-track-color:#FFFF00;
scrollbar-arrow-color:#FFFF00;
and the non-working page has
<style type="text/css">
<!--
body{scrollbar-face-color:#FF0000;
scrollbar-track-color:#FFFF00;
scrollbar-arrow-color:#FFFF00;}
-->
</style>
<link href="5starsA.css" rel="stylesheet" type="text/css" />
be aware that this only works in IE and a lot of people don't like you doing it.
