Controlling a movieclip with the position of the mouse

Good afternoon everyone,

I have been working on a small project at work, I'm trying to controll a movieclip that consists of 60 still images of an aircraft (120 frames total) that when played will show a 360 degree view of said aircraft. I can make it work with buttons, but I ultimately want to control the movieclip by moving the mouse. If anyone can help, that would be wonderful. Thanks in advance.

Here's the code:

import flash.events.MouseEvent;

ac.stop();

stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove);

function mouseMove(event:MouseEvent):void
{
if(mouseX>800 && (mouseX<1600))
{
  ac.gotoAndStop(ac.currentFrame + 1);

  if(ac.currentFrame == 120)
  {
   ac.gotoAndStop(1);
  }
}
else
{
  ac.gotoAndStop(ac.currentFrame - 1);
 
  if(ac.currentFrame == 1)
  {
   ac.gotoAndStop(120);
  }
}
}

Using this code, the SWF acts ok with no errors. I can make the movieclip play in either direction, however, when moving the mouse back in the opposite direction the movieclip continues to play either forwards or backwards.

Thanks,

Tommy
