Blocks No Longer Spawning in Position Defined

Ok, here is my code:

BlockGame.as: (document class)

package 
{

	import flash.display.MovieClip;
	import flash.display.Sprite;
	import flash.events.MouseEvent;
	import flash.ui.Mouse;
	import flash.events.Event;
	import flash.events.KeyboardEvent;
	import flash.utils.getDefinitionByName;

	public class BlockGame extends MovieClip
	{
		public var bank:block_bank;
		public var bg:backgroundImage;
		public var blue:BlueBlock;
		public var green:GreenBlock;
		public var red:RedBlock;
		public var yellow:YellowBlock;
		public var random_color:Number;

		public static var mouse_x:Number;
		public static var mouse_y:Number;

		public function BlockGame()
		{

			var movieArray:Array = new Array();

			movieArray = ["blue","green","red","yellow"];

			for (var i:Number=1; i<=64; i++)
			{
				random_color = Math.floor(Math.random() * 4);

				if ((movieArray[random_color]) == "blue")
				{
					blue = new BlueBlock();
					addChild( blue );
				}
				else if ((movieArray[random_color]) == "green")
				{
					green = new GreenBlock();
					addChild( green );
				}
				else if ((movieArray[random_color]) == "red")
				{
					red = new RedBlock();
					addChild( red );
				}
				else
				{
					yellow = new YellowBlock();
					addChild( yellow );
				}

			}

			bank = new block_bank();
			addChild( bank );

			bg = new backgroundImage();
			addChild( bg );
			setChildIndex( bg, 0 );

			addEventListener(Event.ENTER_FRAME, mouseLocations);

		}

		function mouseLocations(evt:Event)
		{
			mouse_x = stage.mouseX;
			mouse_y = stage.mouseY;
		}

	}

}

BlueBlocks.as: (identical to GreenBlocks and RedBlocks and YellowBlocks)

package 
{
	import flash.events.EventDispatcher;
	import flash.display.MovieClip;
	import flash.events.Event;
	import flash.events.MouseEvent;
	import flash.ui.Mouse;

	public class BlueBlock extends MovieClip
	{
		public var calculations:Array;
		public var box_x:Number;
		public var box_y:Number;
		public var box_size:Number;
		
		public function BlueBlock():void
		{
			this.addEventListener(Event.ENTER_FRAME, sizelocation);

			this.width = 25;
			this.height = 25;

			this.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
			this.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);

			box_x = (Math.round(((Math.random()* block_bank.bank_x ) + block_bank.bank_width )/25)*25);
			box_y = (Math.round(((Math.random()* block_bank.bank_x ) + block_bank.bank_height )/25)*25);
		}


		public function sizelocation(event:Event):void
		{
			this.width = box_size;
			this.height = box_size;

			this.x = box_x;
			this.y = box_y;
		}

		function mouseDownHandler(evt:MouseEvent):void
		{
			Mouse.hide();
			addEventListener(Event.ENTER_FRAME, calculateLocation);
		}


		function mouseUpHandler(evt:MouseEvent):void
		{
			Mouse.show();
			removeEventListener(Event.ENTER_FRAME, calculateLocation);
		}

		function calculateLocation(evt:Event):void
		{
			calculations = Blocks.snapto();
			box_x = calculations[0];
			box_y = calculations[1];
			box_size = calculations[2];
			this.parent.setChildIndex(this, this.parent.numChildren-1);
		}
	}
}

The issue here is that all the blocks come in at 0,0 instead of the random position that it should come in at.
