Google Maps API not functioning properly

Hi all.
I am trying to replicate this sites functionality:
https://google-developers.appspot.com/maps/documentation/javascript/examples/event-arguments

on my page:

http://www.theworldsflight.com/fligh-interaction/flight-suggestions/

If you check out the source code on each page the google api code is essentially identical. I cannot figure out why I am not getting the same result. Is there something that wordpress is doing to make this not work?

Let me know what you think.
Thanks!

Kelly
