simple color change code doesn't work.

[SpaceyFace]

i'm using AS3....i'm trying to change the color of a movie clip after i select a color from the color picker component. when i uncomment the two added lines i get errors. am i just really bad at syntax? i have no idea. this is the ONLY code in the file....i'm close to a deadline on this and i'm at a wall. if someone could guide me i'd REALLY appreciate any help i can get.

i uploaded the flash file here just in case:

the code is as follows:

import fl.events.ColorPickerEvent;

var tempColor = "0x003366";
var aBox:MovieClip = new MovieClip();
drawBox(aBox, 0xFF0000); //draw a red box
addChild(aBox);



aCp.addEventListener(ColorPickerEvent.CHANGE,chang eHandler);

function changeHandler(event:ColorPickerEvent):void {
drawBox(aBox, event.target.selectedColor);
tempColor = aCp.selectedColor.toString();
trace("- " + aCp.selectedColor);
trace("+ ", event.target.hexValue);
//testXc = new Color(_root.testX);
//testX.setRGB("0x" + event.target.hexValue);
}

function drawBox(box:MovieClip,color:uint):void {
box.graphics.beginFill(color, 1);
box.graphics.drawRect(0,0,50,50);
box.graphics.endFill();
}
