Hello fellow programmers. I just wrote this super simple program and for some reason, JGrasp is having a hard time with my discount variables, saying "they may not have been initialized". Check the code out for yourself. I'm sure I'm just missing something but . . .
Also, the letters in bold are the letters that JGrasp is pointing out.
Thanks in advance!
