Scavenger Hunt Game AS3

Hey, I’m trying to make a scavenger hunt game in which I have an array of movieclips on the stage, and I want each movie clip to disappear when it’s clicked on and scored as such. I’ve been playing around with the code and tried using event.target but everything I’ve tried is way off. Here’s my code, it it makes any sense:

stop();

var object_array:Array = new Array();
object_array = [baby,bagpipe,lasso,ladder,beartrap,barbell,slippers,skateboard,headphones,purse];

function removeBaby():void {

//for (var i:int = 0; i < object_array.length; i++) {
//object_array
//object_array.splice(object_array.indexOf(baby),1);
//trace(randomIndex);
//}

}

var Index:int = Math.floor(Math.random()*object_array.length);

function buttonHandler(evt:MouseEvent):void {

for (var i:int = 0; i < object_array.length; i++);
trace(object_array);
object_array.splice(*);
if (object_array.length == 0) {
evt.target.visible = false;

}
}

baby.addEventListener(MouseEvent.CLICK,buttonHandler);
bagpipe.addEventListener(MouseEvent.CLICK,buttonHandler);
lasso.addEventListener(MouseEvent.CLICK,buttonHandler);
ladder.addEventListener(MouseEvent.CLICK,buttonHandler);
