Flash based vending machine

I have created a vending machine in Illustrator and then imported it into Flash. My question is, where can I find the code for the buttons to target the machine window when pressed? Any help would be great.

Here is a rough diagram of what I am looking to do.

post a link to your project with a few more details on exactly what you're trying to get the buttons to do.
