Error problem.

Hi.

I got the error; "The value assigned to variable 'U' might be unused". I have tried to change the letter 'U' to something else, but the error is still existing.

Can someone explain for me what I am doing wrong here?

Regards Cillian

That is not an error, it is a warning. It is telling you that you are assigning a value to a variable ("U" in this case) but that that variable is not used later on. The warning is suggesting that you review your code to see if you made a mistake, and it is also suggesting that if you do not need that variable that you might not need the assignment at all.
