홈페이지 작동은 정상적으로 되고 있는데..

우측 스크롤만 클릭하면 자바스크립트 오류가 떠서

스크롤이 클릭이 안되요 ㅠㅠ


처음에는 게시판 스킨문제인가 생각했는데

모든 페이지에서 동일한 현상이 나타나고 있습니다. ㅠㅠ



======================================================

메시지: 'hotDog.id'은(는) null 이거나 개체가 아닙니다.
줄: 95
문자: 1
코드: 0
URI: http://pie87.com/home/v01/java.js

=======================================================

95번째 줄에는..

while(hotDog.id!="divpop"&&hotDog.tagName!=topDog){

이렇게 적혀있는데

다른 사람들 소스랑 비교해서 봐도 95번째줄에 도대체 뭐가 문제인건지 모르겠어요..

도와주세요 흑흑 ㅠㅠ


아래는 java.js 복사해서 붙입니다 ㅠㅠㅠ
