Failing to make a calculator (Solved but advice still appreciated)

Question

I'm trying to make a calculator. I just want two numbers to add, integer variables X and Y. So far the console has no errors and outputs the first two lines. And independently it outputs both X and Y and can add 1 to them. However when I add them together it just leaves the line blank, no errors.

Code below
