VBA Excel：错误438

Question

我有以下代码，我想测试cell2的值是否重复，所以我在工作表上设置它之后测试了它的条件格式。

它在Excel 2016上运行正常但在2007年没有运行：错误438。

Private Sub CommandButton1_Click()

    Dim LR2 As Long


    With ThisWorkbook.ActiveSheet

        LR2 = .Range("B" & Rows.Count).End(xlUp).Row

        For Each cell2 In .Range("A5:A" & LR2)
            If cell2.Value = "" Then

            cell2.Value = TextBox1.Text
            Exit For

            End If
        Next cell2

        If cell2.Offset(, 1).Text <> 0 Then   

'Error 438 here
            If cell2.DisplayFormat.Interior.Color <> RGB(255, 199, 206) Then

                Label8.Caption = cell2.Offset(, 1).Text
                Label9.Caption = cell2.Offset(, 2).Text
                Label10.Caption = cell2.Offset(, 3).Text
                Label12.Caption = cell2.Offset(, 4).Text
                Label11.Caption = cell2.Offset(, 5).Text
                Label13.Caption = cell2.Offset(, 6).Text
                CommandButton2.Enabled = True

            Else
                cell2.Value = ""
                MsgBox "Votre bac existe déjà", vbExclamation, "Bac double"
                Me.TextBox1.Value = ""

            End If

        Else

        cell2.Value = ""
        MsgBox "Prière de saisir un numéro de bac valide", vbExclamation, "Numéro de bac invalide"
        Me.TextBox1.Value = ""

        End If

    End With
End Sub
