Thanks that thread helped and my JButtons are functional accept for my compute button. I'm trying to call the calculateScores()-method in the my Judging class so it will total all the scores minus the min and max. Both classes are below. Please Help as this has been very frustrating pinpointing my error. Everything compiles it just doesn't run correctly.
