Play movieclip on mousover

Got a bit of a problem in coding something that should be fairly simple. I want to load a movieclip and on mouseover play that clip. Then on mouseout I want that clip to play in reverse back to the first frame. I’m a bit of a noob in scripting and I’ve been driving myself nuts in how to do it. I guess yoyo comes into it somewhere but other than that I’m at a loss. I’d really appreciate any pointers on how to do it.
