Help on flash home page

I need to build a home page in Flash which has multiple demos. I am fairly new to Flash so excuse me if this question sounds basic. I found a web design site that loads a tour demo when you click a button, 9dx.com. I need to do the same thing but I want to load several tours from one home page, depending on which button is pressed. Is there a way to do this without building all the tours into the home page movie? If someone can show me the script I would be very appreciative.
