I'm sure its possible to call functions from other functions, but it is not working for me. Is there some syntax someone can provide to me as an example of calling a function within another function?

Also, both of these functions are in the same class. I have not declared any functions in this class as public or private. Do functions in a class default to private? Or do functions default to public? If they are public by default, are functions in the same class in each other's scope?
