How can I get flash to do an animation on a mouseover

[HokieDrum]

I want to have a top navigation bar for my web site that is done in flash. I will have a few links. When a user mouses over a link, I want a set of sublinks to scroll onto the screen underneath the previous links. How could I go about doing this? Thanks for any help!

check out the movies section-> Interfaces-> Menus-> Roll over menu-final version.
hope it helps

I have a couple questions about that example that is posted. I figured that the way to do this would be to set up all my buttons on the first frame with a 'stop' action and then make a movie clip for each subsequent frame. Then, on a mouseover I would tell any particular button to Gotoandplay the frame with it's movie clip. Unfortunately, this doesn't seem to work...nor does it follow that example. What is the TellTarget part from that example? What parameters does TellTarget take, and what is the best way to deal with this problem? Thanks!
