SetNumber1 패널에서 계좌번호를 받고 SetMoney에서 입금할, 출금할 금액도 받아서 그 번호랑 일치하는 사람(아직 구현 안됨 이것도 몰라서 못하는중)의 계좌 금액을 수정하고 마지막 확인 패널에서 이름, 계좌번호등 정보를 띄워주고 싶은데 도저히 감도 안잡히네요 SetMoney 에서 받은 금액수는 메인으로 넘겨서 저장해두고 마지막 확인 패널에서 출력하려고 코드 만들어놨는데 NULL값만 계속 나와서 뭐가 문제인지...과제로 개별 프로젝트 만들고있는데 초보라 너무 어렵네요 해결책있으면 알려주세요ㅠㅠ 코드 난해한점 양해바랍니다!
