Stopping reverse animation where I want it to stop.

I have some code that reverses the animation on the timeline when an object is rolled over.  I want to add a mouse out event that will then stop that animation dead at the frame it's sitting on when the mouse rolls off of it.  So if the animation is 100 frames long and you rollover this object it'll start playing reverse but if I roll off the object when the animation is at frame 50 it'll stop at frame 50 and won't start up again unless I roll over that object.  I've done something similar to this with a different reverse code but I'd like to try and make it work with this code because it's a much less convoluted chunk of code.  I thought simply putting stop(); as the mouse out function would work since it's referencing local animation but it doesn't.  The animation will not stop until it gets to frame one.  Here's the code I have, can I modify this to do what I want?

right.addEventListener(MouseEvent.MOUSE_OVER, fl_MouseOverHandler);

function fl_MouseOverHandler(event:MouseEvent):void

{

    play()

}

right.addEventListener(MouseEvent.MOUSE_OUT, fl_MouseOutHandler);

function fl_MouseOutHandler(event:MouseEvent):void

{

    stop()

}

left.addEventListener(MouseEvent.MOUSE_OVER, fl_MouseOverHandler_2);

function fl_MouseOverHandler_2(event:MouseEvent):void

{

    var targetFrame:int = 1;

// if we are ahead of the target, start going backwards

if(currentFrame > targetFrame) stage.addEventListener(Event.ENTER_FRAME,goBack);

function goBack(evt:Event):void

{

    prevFrame();

    // kill the event listener when the target is reached

    if(currentFrame <= targetFrame) stage.removeEventListener(Event.ENTER_FRAME,goBack);

}

}

left.addEventListener(MouseEvent.MOUSE_OUT, fl_MouseOutHandler_2);

function fl_MouseOutHandler_2(event:MouseEvent):void

{

    stop()

}
