on(rollover) and on(rollOver) both work,but I'm not sure if it's case sensitive?开发者_StackOverflow社区
A simple Google search has turned up: AS 1.0 was NOT case-sensitive, AS 2.0 and 3.0 ARE case-sensitive.
But, Have you double checked your variable usage to make sure that you don't have variables with those names in scope?
