AS3 With Movie Clip Buttons

programming flash
1

Whats up guys, first post here. I was wondering if you guys could give me some input as to how I might do a couple of things. I have four movie clip buttons for my website that work great. A Home, Media, About Me, and Contact button. My problem is that I want to use as3 to be able to add a loadMovie type function to each button when clicked. This would load an external swf file, that would have information in each swf for home, media etc. I can’t exactly find a tutorial, or example code that would flow with my current coded buttons. Also im not 100% sure about how i could load the external swf in a specific location. Any links to a tutorial or some help is much appreciated!

Ps: This is the code I am currently using.

btn_mc.buttonMode = true;
btn_mc.addEventListener(MouseEvent.ROLL_OVER, onButtonOver);
btn_mc.addEventListener(MouseEvent.ROLL_OUT, onButtonOut);

btn_mc1.buttonMode = true;
btn_mc1.addEventListener(MouseEvent.ROLL_OVER, onButtonOver);
btn_mc1.addEventListener(MouseEvent.ROLL_OUT, onButtonOut);

btn_mc2.buttonMode = true;
btn_mc2.addEventListener(MouseEvent.ROLL_OVER, onButtonOver);
btn_mc2.addEventListener(MouseEvent.ROLL_OUT, onButtonOut);

btn_mc3.buttonMode = true;
btn_mc3.addEventListener(MouseEvent.ROLL_OVER, onButtonOver);
btn_mc3.addEventListener(MouseEvent.ROLL_OUT, onButtonOut);

                    
function onButtonOver(e:MouseEvent):void
{
    e.currentTarget.gotoAndPlay("over");
}

function onButtonOut(e:MouseEvent):void
{
    e.currentTarget.gotoAndPlay("out");
}
