Import not working

programming flash
1

I import a class(this is in a .as file for flash CS5.)
I define it and clearly I later instantiate it

[CENTER]


import com.greensock.TweenMax;

public class Turret extends MovieClip
	{
		.....
                public var TweenMax:TweenMax;
        }

private function loop(e:Event)
		{
			.....

                         if (x > stage.width - xBound)
			{
				removeEventListener(Event.ENTER_FRAME, loop);
				TweenMax.to(this, tweenTime, {x: 700 - 17.5, scaleX:.2, scaleY:.2, rotation:755});
			}
			else if (x < xBound)
			{
				removeEventListener(Event.ENTER_FRAME, loop);
				TweenMax.to(this, tweenTime, {x: 17.5, scaleX:.2, scaleY:.2, rotation:-755});
			}


			if (y > stage.height - yBound)
			{
				removeEventListener(Event.ENTER_FRAME, loop);
				TweenMax.to(this, tweenTime, {y: 500 - 5, scaleX:.2, scaleY:.2, rotation:-755});
			}
			else if (y < yBound)
			{
				removeEventListener(Event.ENTER_FRAME, loop);
				TweenMax.to(this, tweenTime, {y: 5, scaleX:.2, scaleY:.2, rotation:-755});
			}
     }
