Complete flash site tutorial problems pls help!

I’m creating a site based on the tutorial: “build a complete flash site” I’ve re-created this for my design and it works fine.

The problem i have is in the tutorial the first page has no content, just buttons.

What i want it for the home page to be shown when loaded, then when a button is clicked an external swf is loaded.

I’m sure this is simple code, but i’m a noob in flash.

please help

Thanks in advance
