그래서이, 내 자신의 질문의 솔루션입니다 그것은 나를

 function checkEBASComplete() 
     local tempScore = 0 
     for i = 1, #ebasRating_Arr do 
      print("EBAS:"..ebasRating_Arr[i]) 
      tempScore = tempScore + ebasRating_Arr[i] 
      if (ebasRating_Arr[i] == -1) then 
       ebasScore = 0 
       ebasScore_text.text = "Test Incomplete" 
      else 
       ebasScore = tempScore 
       ebasScore_text.text = tostring(ebasScore) 
      end 

     end 

     tempScore = 0 
    end
