Links and thumbnails - how do I target these?

I made a function like this:

function cleanStage():void{
	if(container_mc != null){
		while (container_mc.numChildren > 0){
		  container_mc.removeChildAt(0);
	}
		while (container_thumbs.numChildren > 0){
		  container_thumbs.removeChildAt(0);
	}
	}
}

And then use it in the function that changes the frame like this:

function goHome (e:MouseEvent):void{
	cleanStage();
	gotoAndStop("Home");
}

It seems to run without error. This is probably a horrible way to solve these things from a professional point of view, but I can only do what seems the most natural to me since I dont have any real training in flash

That's pretty much what I meant, but I was going to use a level of indirection instead of checking within cleanStage whether it applied. Something like this:

var cleanup:Function = cleanLinks;

function goHome (e:MouseEvent):void{
	cleanUp();
	gotoAndStop("Home");
}

function cleanLinks():void{
	while (container_mc.numChildren > 0){
	  container_mc.removeChildAt(0);
	}
}

function noop():void{}

function cleanSomethingElse():void{
  //whatever you have to do to clean up a different state.
}

And you could set cleanup to be whichever cleaning function applies when you enter a frame or state.

Okay, so a function variable is basically a variable that is a function, and you define the function of the variable by assigning different functions to it. So if I wanted to clean after being on the "Gallery" page of my site I could make a function called "cleanGallery" and assign it to the cleanup variable?

That is really cool functionality! I will have to remember that for later.

Yes, exactly. Notice I defined a noop (as in no operation) function. This is a little easier to handle than checking for the function variable being null in the case where you don't want to do anything.
