I did notice that in the JavaScript code for the menu there were a few HTML comment tags within the code. When you copy the code out to the file menu.js remember to take these out. Also, remove the <script> and </script> from the top and bottom of the file. Replace this section of the HTML page with reference to the file so that your page's HTML has this section where that code used to be:
Code:
<link rel="StyleSheet" href="ChMenu00.css" type="text/css">
<script type="text/javascript" src="menu.js"></script>
I did this with a local copy of your page and it seemed to work out okay. The script section in the page where it computes and prints the current date can be left as it is. For more exact reference, the section of the HTML page that you want to take out to place into the menu.js file goes from line 17 to line 261. The menu.js file comes out to about 10k in size, so if the browser caches this file (as it should) it will reduce your bandwidth consumption and your page should load a bit faster.
