Loading/Unloading - swfs inside of swfs

programming flash
1

Here we go…

I have a main.swf.

Main.swf contains 4 buttons(about, portfolio, contact, clients).

These for buttons call in external swfs(ex. portfolio.swf) into an empty movie clip on the main.swf stage.

inside portfolio.swf are three more buttons(print, web, logos)

When you click on one of these buttons they need to call in another external swf(web.swf) and also remove itself(portfolio.swf)

That is where I run into my problem.

this is the code i am using for the original buttons on the main.swf:

function initMovieLoad(path) {
movieToBeLoaded = path;
if(!initializedExternalMovies) {
initializedExternalMovies = true;
loadNewMovie();
} else {
target.gotoAndPlay('midpoint'); 
}
}

_global.loadNewMovie = function() {
target.unloadMovie(); 
target.loadMovie(movieToBeLoaded); 
target._y=-130;
target._x= -160;
}


var mc:MovieClip = this.createEmptyMovieClip('target', this.getNextHighestDepth());

initMovieLoad('intro.swf');

this.homeBTN.onRelease = function() {
initMovieLoad('home.swf'); 
}

this.aboutBTN.onRelease = function() {
initMovieLoad('about.swf'); 
}

this.portfolioBTN.onRelease = function() {
initMovieLoad('portfolio.swf'); 
}

this.clientsBTN.onRelease = function() {
initMovieLoad('clients.swf'); 
}

this.contactBTN.onRelease = function() {
initMovieLoad('contact.swf'); 
}

I thought I could just place this code inside the portfolio.swf and boom, everything would be set. but it didnt work.

I need to know how to call from the main.swf that web button inside of the portfolio.swf to bring in the web.swf

Any ideas would help at this point. THX
