How to differentiate 3rdPersonCharecter and its child?

Hey ClockworkOcean. Thanks so much. I really appreciate the help. Okay so I see now that the cast is not working. It complies with no problem but its not firing off a print sting and fail. I also tried the child of Enemy AI and no luck. So the question is I cant cast to my child? Do i have to make an Enemy AI completely separate from scratch and then cast to that? I think that why they are all connected. Is it possible. to get the child separate? I know they have there own controller but thats not working either. Thanks
