I think you need to include
Comparing your code to mine and I have done lots of Propmaps
This line
<script type="text/javascript" src="http://ivyleaguekids.com/google_javascript/wagmp_map_2.js">/*wagmp*/</script>
should be:
<script type="text/javascript">
/*wagmp*/
<!--#include file="http://ivyleaguekids.com/google_javascript/wagmp_map_2.asp" -->
</script>
Hope this helps

Jon
