I might just be massively retarded but I’m having trouble adding or removing event listeners within functions… I know this has worked for me before but I seem to be doing something wrong now.

Sigh… If anyone can explain to me why I’m recieving ReferenceError: Error #1069: Property ROLL\_OUT not found on flash.events.MouseEvent and there is no default value. I’d appreciate it a ton!

It’s just a simple removeEventListener within a rollover/rollout function…

Aargh!

Thanks in advance 🙂
