I’ve done the turoial for xml gallery with thumbnails. I modified it to add some animations and my prev/next buttons are now inside of a movie clip. They don’e work any more. None of the code has change just the positio of the buttons in my movie.

Here is a piece of the code that makes the buttons work.

listen = new Object();  
listen.onKeyDown = function() {  
if (Key.getCode() == Key.LEFT) {  
prevImage();  
} else if (Key.getCode() == Key.RIGHT) {  
nextImage();  
}  
};  
Key.addListener(listen);  
previous\_btn.onRelease = function() {  
prevImage();  
};  
next\_btn.onRelease = function() {  
nextImage();  
};

According to what I understand from the tutorial, this function uses instance names. The buttons should work no matter where the buttons are in the movie.
