a few things i see in your page.
it looks like you are loading a jquery map plugin:
<script type="text/javascript" src="ScriptLibrary/jquery.gmap.min.js"></script>
<link rel="stylesheet" type="text/css" href="Styles/dmxCalendar2.css" />
<link rel="stylesheet" type="text/css" href="Styles/jqueryui/redmond/redmond.css" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
also at the top of your page, you have 2 head sections:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script type="text/javascript" src="../CSSMenuWriter/cssmw0/menu.js"></script>
<style type="text/css" media="all">
<!--
@import url("../CSSMenuWriter/cssmw0/menu.css");
-->
</style>
<!--[if lte IE 6]>
<style type="text/css" media="all">
@import url("../CSSMenuWriter/cssmw0/menu_ie.css");
