Passing variable to URLRequest

1

Could someone help me with this? I’m unclear as to why this bit of code won’t work and my eyeballs are about ready to pop Is it not possible to assign a URL to a variable and then pass that variable back to the URLRequest? I’m getting two errors:

1151: A conflict exists with definition movieURL in namespace internal.
Warning: 3596: Duplicate variable definition.

I’ve attached the code below, any help would be GREATLY appreciated.

var movieURL:String = new String();
var movieURL = “flash/pages/web/projects/webUNM.swf”;

var movieLoader:Loader=new Loader();
stage.addChild(movieLoader);
movieLoader.x=225; movieLoader.y=20;

var listStyleNorm:TextFormat = new TextFormat();
listStyleNorm.color = 0x000000;
var listStyleOver:TextFormat = new TextFormat();
listStyleOver.color = 0xffffff;

function menuButton(mc:MovieClip):void {
mc.addEventListener(MouseEvent.MOUSE_OVER, menuOver);
mc.addEventListener(MouseEvent.MOUSE_OUT, menuOut);
mc.addEventListener(MouseEvent.MOUSE_UP, menuLoad);
};
function menuOver(e:MouseEvent):void {
e.currentTarget.t.setTextFormat(listStyleOver);
};
function menuOut(e:MouseEvent):void {
e.currentTarget.t.setTextFormat(listStyleNorm);
};
function menuLoad(e:MouseEvent):void {
fadeMovie=new Tween(movieLoader, “alpha”, Regular.easeIn, 0, 1, 1, true);
var movieReq:URLRequest=new URLRequest(movieURL);
movieLoader.load(movieReq);
stage.addChild(movieLoader);
};
// Set up buttons
menuButton(webMenu_mc.projUNM_mc);
