I’m having a bit of trouble figuring out why I can’t trigger the function _playUntil_, which is another private function in this class, in this snippet. This is all residing in a class, and I’m wondering if that is what is making things tricky. Any help would be great. I tried tracing out _currentTween.obj_ as well as _currentDestination_, both of which return _undefined_. Any help would be tremendous.

\*private function processListenerInfo( listenerInfo:String ):Void {  
setCurrentDestinationTo( listenerInfo );  
if (( currentDestination != currentLocation ) && (currentDestination)) {  
currentTween = new Tween(chapterSpawnLocation, “\_alpha”, Strong.easeIn, chapterSpawnLocation.\_alpha, 0, .4, true);  
currentTween.onMotionFinished = function() {  
playUntil( currentDestination );  
}  
}
