If you are trying to create flash buttons, I must warn you:
Your clients (the people who view your site) will be required to have Flash on their computer, and they will have to click the flash buttons before they are activated, requiring someone to click on the button more than once for each page. You might find you are better off creating some buttons from PNG or JPEG files, and then making what I think are called "over" images, where moving the house causes the button to highlight. This is not only faster in some cases, but will also not require your users to have Flash.
