当我运行此模块时，我得到一个“需要对象”错误。我是VBA新手，我不知道代码有什么问题。

Sub CountOccurances()
Dim Total As Integer
Dim Column As Integer
Dim Row As Integer

Total = 0
For Column = 2 To 51
    If Worksheets("Sheet1").[13,Column].Value = 1 Then
        For Row = 12 To 16
          If Worksheets("Sheet1").[Row, Column].Value = 2 Then Worksheets("Sheet1").[20,Row+8].Value = Total + 1
        Next Row
    End If
Next Column
End Sub

我试过几次修改，但都没有成功。
