movieclip chain/propagation, need help

[Onakanta4]

I am trying to get a visual volume control type effect with movieclip boxes and clicking. So far I can do it, but the code is probably not optimal. I am trying to write it so I can include more or less movieclips in the future without rewriting all the code every time. Is there a better way to do this?

var mc:MovieClip = new MovieClip();
mc.graphics.beginFill(0xFF0000);
mc.graphics.drawRect(60, 20, 100, 80);
mc.graphics.endFill();
mc.label = "mc"
addChild(mc);

var mc1:MovieClip = new MovieClip();
mc1.graphics.beginFill(0xCCFF00);
mc1.graphics.drawRect(60, 120, 100, 80);
mc1.graphics.endFill();
mc1.label = "mc1"
mc.addChild(mc1);

var mc2:MovieClip = new MovieClip();
mc2.graphics.beginFill(0x66CC66);
mc2.graphics.drawRect(60, 220, 100, 80);
mc2.graphics.endFill();
mc2.label = "mc2"
mc1.addChild(mc2);

var mc3:MovieClip = new MovieClip();
mc3.graphics.beginFill(0x63B8FF);
mc3.graphics.drawRect(60, 320, 100, 80);
mc3.graphics.endFill();
mc3.label = "mc3"
mc2.addChild(mc3);

mc.addEventListener(MouseEvent.CLICK, mc_clicked);
mc1.addEventListener(MouseEvent.CLICK, mc_clicked);
mc2.addEventListener(MouseEvent.CLICK, mc_clicked);
mc3.addEventListener(MouseEvent.CLICK, mc_clicked);

function mc_clicked(event:MouseEvent):void {

    mc.alpha = 1
    mc1.alpha = 1
    mc2.alpha = 1
    mc3.alpha = 1
    
    if(event.target.alpha < 1){
        event.target.alpha = 1;
    }else{
        event.target.alpha = .4;
    }
}

var marr:Array=new Array
for (var i:int=0;i<5;i++){
var mc:MovieClip = new MovieClip();
mc.graphics.beginFill(0x66CC66);
mc.graphics.drawRect(60, 20+i*100, 100, 80);
mc.graphics.endFill();
mc.label = "mc"+i
addChild(mc);
mc.addEventListener(MouseEvent.CLICK, mc_clicked);
mc.addEventListener("otherclicked",revertcolor);
marr.push(mc)
}

function mc_clicked(event:MouseEvent):void {
event.target.dispatchEvent(new Event("otherclicked"))
event.target.alpha = .4;
}

function revertcolor(e:Event):void{
e.target.alpha =1
}

something like this?

Thanks, that's sort of what I was looking for, except that the squares should only fade in sequence, depending on where you click, and not individually.
