How to best structure/code a website or presentation

I’m trying to figure out what is the best way to structure a simple interactive presentation in Flash - I only got a few months programming experience.
Mine is as such:

home_mc // contains buttons hbtn1_mc
page1_mc

I have labeled frames on and off to allow for animation of pages elements.
And in the root timeline the actionscript is as such:

this.onLoad = function () {
this.home_mc.gotoAndStop(“on”);}

this.home_mc.hbtn1_mc.onRelease = function () {
this.p1_mc.gotoAndStop(“on”);
this.home_mc.gotoAndStop(“off”);
}

But it doesn’t work! Can you offer any ideas suggestions, or your way to structure this sort of project?
