Creating a 4-sectioned site with transitions [renamed]

hi everyone!

i have to make a site consisting of 4 sections, inside these swf i want to have buttons that should load any other of the site’s sections and do a transition between what is loaded and the next swf.

i’ve been working with AS3 for just 3 months and learning OOP as i go, kicking and screaming…
so yeah, what would be the structure to do something like this??

let’s trip the light fantastic :megaman:
