alright, so i hit the bottom button after filling out the form and this error comes up "아이디 사용가능여부를 확인해주세요" in english it says "Please check ID availability" and i do, and when i click on the ID availability button it says
"콜백 함수 호출시 오류가 발생하였습니다.
(콜백함수가 존재하지 않을 가능성이 높습니다.)"
which translated to english means
"An error occurred when calling the callback function.
(Callback function does not exist is more likely.)"
so does anyone think they can help me out here?
