ANother newbie question: site architecture

Hi All,

My apologies for the simple question:
If I wanted to implement a simple site with a sidebar, where the content of
the main area switches to different pages, how would I implement it in flash
CS3? Is it like finding some component which accepts swf files as source and
telling the sidebar buttons to switch the source on this component?

I feel I am missing something important here...

Thanks,

Ari
