When i load your map, it gives an error about the google api key.the code for the api key is:
<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&key=[ABQIAAAAb8yIfRrzLUBIGTUJ_comsBTgNyTH6bIgqdkHNhvaUK2UMRkOFhRwwcoH7OtzJwDN1fLXInRWTpbu0w]">/*wagmp*/</script>
you have the api key surrounded by square brackets, these need to be removed.
<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAb8yIfRrzLUBIGTUJ_comsBTgNyTH6bIgqdkHNhvaUK2UMRkOFhRwwcoH7OtzJwDN1fLXInRWTpbu0w">/*wagmp*/</script>
