Hi dzulfriday. What a lot of people here have suggested should work. It is possible that you have written your css the right way, but have also declared a global list-style-type some where below #top-ad li list-style-type. I would make sure that this is not the case. If you find it is still happening even after looking through your css for any overriding styles, I would try to get your css and html up somewhere for us to review it.
