idk what went wrong with yours (possible problems include: gave wrong unit wrong ability, used wrong ability as base (idk about the (old) things), etc).

anyway i made you a map which shows the minimum modifications needed for making a mount spell. you can see them in the object editor with pink in the unit and ability tabs.
