Function not defined

Question

I am getting a function not defined error with my jquery script and i'm not sure why.

JQuery Code: http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAhTrgZ5jvdqcEQouEpPcZ_hS81NmJwGXlxuJr8lEEo4Njw3WRVhT8auzZb55JSMDkwIaCdNkPHL5gNg" type="text/javascript">

Problem: Anyway, as you can see in the code i am first setting all of the variables (including the customerName and customerAddress, which are the most important in this case). Then i have four functions and at the end of the script i initialize the map. Everything works except for two things on the html page. There is an "onClick" to center the map that is not working and the form submit does not work.

I believe this is because i have the functions set inside the ready handler. I have been told that i need to bind the functions to their events within that handler just as i have with initialize_map. I have tried to do this but everything i try does not work. Side note and helpful tip maybe: show_address runs immediately to start the map when i call initialize_map; however, it is also what is supposed to be called when you click the button "Center Map on Dealership". get_directions is only called when you submit the form.

As of now everything shows up right when the page loads; however, when i click on "Center map on Dealership" or submit the form i get a javascript error that is telling me that the function is not defined.

I am at a standstill with this. Not sure how to get this functioning properly. Any help is greatly appreciated. Thanks!

It's because your show_address and get_directions are defined only inside that document.ready handler's scope, you need to move the functions outside there if you want to call them via inline script.
