Restricting Paste on different Data Validations columns in the same worksheet

[Retrorock]

Hi all,

I found this code off

https://superuser.com/questions/870926/restrict-paste-into-dropdown-cells-in-excel?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa

in order to do what i wanted, which is to restrict people from pasting over and thus deleting my data validation in a shared workbook, however an error comes up if I tried to set the DataValidationRange to include multiple column with different data validation (some validations are list, some are date and so on).

Private Sub Worksheet_Change(ByVal Target As Range)    'Does the validation range still have validation?
    If HasValidation(Range("DataValidationRange")) Then
        Exit Sub
    Else
        Application.Undo
        MsgBox "Error: You cannot paste data into these cells." & _
        "Please use the drop-down to enter data instead.", vbCritical
    End If
End Sub


Private Function HasValidation(r) As Boolean
    'Returns True if every cell in Range r uses Data Validation
    On Error Resume Next
    x = r.Validation.Type
    If Err.Number = 0 Then HasValidation = True Else HasValidation = False
End Function

So I tried to set up a separate instant for each column I have (Name column A as DataValidationRange1, Column C with a different data validation as DataValidationRange2) and edited the code as so to include two If scenario, but an error still comes up, not sure why. Can Anyone help advise me on this?

Private Sub Worksheet_Change(ByVal Target As Range)    'Does the validation range still have validation?
    If HasValidation(Range("DataValidationRange1")) Then
        Exit Sub
    Else
        Application.Undo
        MsgBox "Error: You cannot paste data into these cells." & _
        "Please use the drop-down to enter data instead.", vbCritical
    End If

    If HasValidation(Range("DataValidationRange2")) Then
        Exit Sub
    Else
        Application.Undo
        MsgBox "Error: You cannot paste data into these cells." & _
        "Please use the drop-down to enter data instead.", vbCritical
    End If


End Sub


Private Function HasValidation(r) As Boolean
    'Returns True if every cell in Range r uses Data Validation
    On Error Resume Next
    x = r.Validation.Type
    If Err.Number = 0 Then HasValidation = True Else HasValidation = False
End Function
