How Do I Access Data Elements Of Another File-Class In A Different File Class

Well the first thing you need to understand is we can't see your code, your screen or read your mind. We would have no idea at all what you have tried but just say that "i cant get access to it". "I can't" is not at all a helpful description of a problem. If it were me, I would instantiate the "other" class in my class and start using it. I do it all the time. What you have done to prevent this from occurring is kind of hard to say.
