Need an event listener for when a movie clip is finished playing

This is a simple enough question. I have a slideshow that loads an image via XML, then adds said image to a placeholder inside a movie clip, and then proceeds to play a little sliding animation via the movie clip. What I need to do is figure out how to get an event that the movie clip is finished and sitting back on frame 1 so that I can run a “nextImage” function that loads the next image from the XML. I’m pretty new to actionscript, and I can’t for the life of me figure out how to properly handle what should be a simple event. If I put a simple listener at the end of the movieclip, it doesn’t talk to the main script at all?

How would you guys go about this? I don’t want to use a timer…
