External .swf file

I’m new to everything flash.
I’m trying a very simple website using flash mx which I learned from kirupa.com “creating a full flash site”. once I got every cleared I will move on to do a much better one for now the basics.

Through their example they have a web structure
which are index and the contents.

Now I can I load a movie in the main index where this loaded movie is also an index where there a buttons and other stuffs.

I tried it once but it didn’t work at least the buttons.
Is there a way to do it.
