Populating an array with sprites

programming flash
1

I’m making an array and populating it with a for loop. I have no problem doing this with a movieclip from the library, but when I attempt to use a Sprite called OneMillion instead using the same script I keep getting the message:

1180: Call to a possibly undefined method OneMillion.

Here’s the code and it works perfectly if I use a movieclip linked from the library:

var arrayCount:Number=1000;
var loopCount:Number=1000;

var numRows:Number=132;
var numColumns:Number=200;
var hSpace:Number=1.25;
var vSpace:Number=4.75;

var deficitScreen:Sprite=new Sprite();
deficitScreen.x=30;
deficitScreen.y=30;
addChild(deficitScreen);
deficitScreen.rotation=-90;

var OneMillion:Sprite=new Sprite();
OneMillion.graphics.beginFill(0x990000);
OneMillion.graphics.drawRect(0,0,1,3);

var aMillions:Array=new Array();
makeArray();
function makeArray():void {
    for (var i:Number=0; i<1000; i++) {
        var currentRow:int=Math.floor(i/numColumns);
        var currentColumn:int=i-(currentRow*numColumns);
        aMillions*=new OneMillion();
        deficitScreen.addChild(aMillions*);
        aMillions*.x=currentColumn*hSpace;
        aMillions*.y=currentRow*vSpace;
        aMillions*.alpha=1;
        //trace(aMillions.length);
    }
}
