선생님 안녕하세요 코드 적용 후 에러가 발생하고 있습니다 ㅠㅠ

Question

벌써 두시간 째 원인 파악 하고 있는데 도저히 찾을 수가 없네요 선생님 도와 주세요 breakpoint 찍어봐도 제가 실력이 부족해서 지금까지 잘 해 왔는데 갑자기 이러니까 너무 슬프네요 살려주세요! 코드 첨부해드리겠습니다.

js에서, messageA_tranlateY_in 과 messageA_tranlateY_out 이라고 오타가 있는 부분이 있네요^^ Ctrl + F로 tranlate 라고 쓰신 부분을 찾아서, translate 로 바꾸어주세요~ ( s 가 빠졌습니다)
