에러가 뜨는데..

버전은 0.5.1입니다.

영상과 똑같이 작성했고 뭐가 문제인지 잘 모르겠어서 질문 드립니다~

function addCandidator ~ public owner {
function upVote~ public {
function finishvote~public onlyowner{이 세부분이 에러났습니다.

brower/vote.sol : 40:5 DeclarationError: Identifier already declared.

function addCandidator(string _name) public onlyowner {

^(relevant source part starts here and spans across multiple lines).

brower/vote.sol : 20:5: the previous declaration is here:

event addCandidator(string name);

^---------------------------------------------^

이라고 써져 있고요. 볼드 처리한 곧은 전부 동일한 에러입니다.
