When i view source of your page I see the following at the top:
<script type="text/javascript" src="google_javascript/wagmp_map_6.js">/*wagmp*/</script>
<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAAYjC13GfkbKRCKF_zBjqhBRuRkmfJn3fDiHectdW2tOoSFegJxRLYwFDGFdXLNJmGGyAbCvkQ3Ccfg">/*wagmp*/</script>
<script type="text/javascript" src="google_javascript/wagmp_map_5.js">/*wagmp*/</script>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
1) Those script tags should not come before the doctype tag. They need to be moved so they are between the <head> and </head> tags.
2) If I try to open those scripts, I get a 404 page not found error .please make sure to upload the entire google_javascript folder to the server.
