excel vba运行错误424：要求对象。 求教！！

Sub cmpprice()
Dim i, j As Integer
Dim rng, rng1 As Range
' i<=2627
For i = 2 To 5
j = i + 1
If Cells(i, "C") = Cells(j, "C") Then
rng.Value = Cells(i, "O")
rng1.Value = Cells(j, "O")
rng.Interior.Color = RGB(255, 0, 0)
rng1.Interior.Color = RGB(255, 0, 0)
End If
Next

End Sub

Answer 1

cells() 应该是只允许数字吧，你把 ‘C’ 改成3； ‘O’改成15 试试

Answer 2

直接说你要什么效果

追问

比较两个单元格中内容，如果内容相同，将这两个的单元格显示红色

追答

Sub cmpprice()
Dim i As Integer, j As Integer '这里一定要两个变量都写上类型，否则不写的就是变体
For i = 2 To 5
j = i + 1
If Cells(i, "C") = Cells(j, "C") Then
Cells(i, "O").Interior.Color = vbRed
Cells(j, "O").Interior.Color = vbRed
End If
Next
End Sub
多看些基础的，定义RNG 为range类型后，要用
SET rng = Cells(i, "O")
SET RNG1=CELLS(J,"O")
这样才可以把变量当单元格。

另外定义要这样，
Dim rng as range , rng1 As Range
