Oleg—thanks so much for your response. I’ve kept trying to get this to work but no luck. I’ve noticed I only get the error message when I paste the expression into a layer with more than one keyframe. (See attached screen cap.) One keyframe, no error message, two keyframes, error message. Is this a clue?
Incidentally, even when I get the expression successfully placed into the layer, the behavior doesn’t even work. There’s no bounce/decay/stop.
