ok, make multiple layers, each one being a frame of the animation with the first layer (bottom in the layers pallet) as the first frame, and then each layer going up is the next one. Once you have all your layers created and ordered, go to "save for web" choose the gif format, and hit the button for "animate (checkbox actually). this should open up a new area of the menu, which is pretty self explanatory. Before you save it though, make sure you hit the little E button on the bottom of the preview to preview the animation in Internet explorer. Once you have it the way you want it, save it as a gif, and upload it here...
