Attach a sound to a door motion

Chris:I have created a door motion in a matinee. At the beginning of the motion I have attached a door open sound after the click event. I need to make a similar sound go off after the door closes. I can get the sound to work but it fires off at the beginning of the close. I can make it work with a delay node, but if the door gets stopped in the middle of it’s motion the sound will fire off at the wrong time. How can I get it to play at the end of its motion.
