Code:
package
{
	import flash.display.Sprite;
	import flash.events.*;
	public class MagnetGolf extends Sprite
	{
		public var puck:Puck;
		public var puckVX:Number;
		public var puckVY:Number;
		public var minusCharges:Array;
		
		public function MagnetGolf()
		{
			puck = new Puck();
			addChild(puck);
			puck.x = 20;
			puck.y = 240;
			
			puckVX = 1;
			puckVY = 0;
			
			plusCharges = new Array();
			for (var i:int = 0; i < 5; ++i)
			{
				var c:MinusCharge = new MinusCharge();
				addChild(c);
				c.x = Math.random() * 550;
				c.y = Math.random() * 400;
				minusCharges.push(c);
			}
			
			addEventListener(Event.ENTER_FRAME, update, false, 0, true);
		}
		
		function update(e:*=null):void
		{
			puck.x += puckVX;
			puck.y += puckVY;
		}
	}
}
The error is one of the output ones, which give no info on why I get the error.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at MagnetGolf()
Something that might help: If I take away the line minusCharges.push(c); it doesn't give me that error. So I assume c doesn't exist yet?? But i added it a couple of lines up with addChild! Help please!
