Thanks for the assistance everybody. The issue was not with the global var. Since that was named outside of a function it was global. What I had to do was call the initialize function before my map call. I originally had the initialize function called in my html body onload. Apparently in Firefox, the Javascript is run before the HTML, as opposed to IE which runs all of your HTML first. I was unaware of this. The page works great now!
Thanks to Google for a great API tool. I especially appreciate the bicycle path, and look forward to when the transit data is available through the API. Thanks again to all!
