Hi, firstly, your html is totally out whack - this is the structure of your page :
<html dir=ltr lang=en-us>
<head dir=ltr lang=en-us>
(...)
</head>
<body dir=ltr lang=en-us>
<table width="100%" cellpadding=0 cellspacing=10px>
<tr><td colspan=2>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
</head>
<body>
</body>
</html>
</td></tr>
<tr><td colspan=2><hr></td></tr>
<tr>
<td valign=top width=200px><html>
<head>
<style type="text/css">
</style>
<script type="text/javascript">
</script>
</head>
<body>
<div class=sidebarmenu>
/div>
</body>
</html>
when it should be :
<html>
<head>
// all meta tags, css etc here
</head>
<body>
// all content here
</body>
</html>
also you shouldn't use tables for page layout
It would be a good idea if you read some stuff about html and basic page structure
