I have a button in my website that has both functions(MOUSE\_OVER and MOUSE\_OUT), and when i mouse\_over in the button it expands its size, but when i mouse\_out it’s supposed to change back to it’s original size, except it doens’t.

The code i have is:

```auto
aboutb.addEventListener(MouseEvent.MOUSE_OVER, about_anim);

function about_anim (e:MouseEvent) :void{
    aboutb.nextFrame(); //in the next frame is the expanding animation 
    
aboutb.addEventListener(MouseEvent.MOUSE_OUT, about_anim_out); // to add the mouse_out function

    }

function about_anim_out (e:MouseEvent) :void{
    aboutb.prevFrame();
}

```

Am i doing anything wrong?
