    Default Multiple Google Maps on One page with Advanced Directions

    Hello,
    I am trying to create multiple google maps with multiple directions that load on one page. I have tried duplicating the var and function names but I haven't been able to get it to work.

    Does anyone have any ideas?

    Any help or suggestions would be greatly appreciated!

    Hi,
    I ended up figuring it out.

    An example is here: http://topianno.com/testing/google-API.html

    Oh, okay. I use firebugs net and javascript panel when I'm not sure what's happening. It'll show you the current outputs and you can trouble shoot from there, most of the time.
