Animated gifs in F8

Hi. I use Flash to create animated GIF banner ads. I exparamented using some of the new filters in F8 to export as a GIF. When its a static gif, it works fine, but when its animated, it doesnt work (attached is a sample). Is there an option somewhere in publish settigns that I’m missing? any ideas? Also attached is a SWF of what it is supposed to look like.
