Alright, I think I understand what you're trying to do, but I still don't know what your question is.

Let me try to be more specific on what we need. Does your program compile without any warning? Is the program that you've shown working or failing? Or is it doing something, but not quite what you want? In which way is it not doing what you want? If possible, please show input data as well as current result versus expected result. In short, please help us to help you.
