Answer 1

Thank you that was it

Answer 2

This link says that variable names are case sensitive.

Does it work when you use 'N'

Answer 3

Sorry in you case that is not the fault.

It is the ; behind the for-loop
for(int n = 2; n<= 12; n++); <-

The semicolon ends the for-loop before it even can start with it body.

Some code to prove my statement.
