Expand current on change to include multiple target ranges

Question

I have a piece of code that does exactly as I want it to do. Whenever a cell is updated in the column "Contacts 1 Made?" it inputs the date and time into the 2 columns to the right. I want to expand the target range though to include 2 other columns that aren't adjoined. These column headers are;

• Contact 2 Made?
• Contact 3 Made?
• Appointed

I want to same basic principles to apply to these columns. Whenever a cell is updated in any of these columns I want it to do the same thing and input the date and time in the cells to the right.

Private Sub Worksheet_Change(ByVal Target As Range)

Dim KeyCells As Range

Set KeyCells = ActiveSheet.ListObjects("VAMP_P1___P2").ListColumns("Contact 1 Made?").Range

If Not Application.Intersect(KeyCells, Range(Target.Address)) _
Is Nothing Then

Application.EnableEvents = False
If Target.Value <> "" Then
ActiveCell.Offset(0, 1).Value = Format(Now(), "dd/mm/yyyy")
ActiveCell.Offset(0, 2).Value = Format(Now(), "hh:mm")
Else
ActiveCell.Offset(0, 1).Value = ""
ActiveCell.Offset(0, 2).Value = ""
End If
    
End If

Application.EnableEvents = True

End Sub

I tried to update the keycell range using the intersect shown below but when it runs it debugs with Invalid procedure call or argument

Set KeyCells = Intersect(ActiveSheet.ListObjects("VAMP_P1___P2").ListColumns("Contact 1 Made?").Range, ActiveSheet.ListObjects("VAMP_P1___P2").ListColumns("Contact 2 Made?").Range)

A Worksheet Change: Date and Time Stamps

    Const TABLE_NAME As String = "VAMP_P1___P2"
    Const DATE_COLUMN_OFFSET As Long = 1

    Const TIME_FORMAT As String = "hh:mm"
    Dim Titles() As Variant: Titles = Array( _
        "Contact 1 Made?", _
        "Contact 2 Made?", _
        "Contact 3 Made?", _

    Dim trg As Range

    Dim TimeNow As Date: TimeNow = Now
    Dim DateString As String: DateString = Format(TimeNow, DATE_FORMAT)
    Dim TimeString As String: TimeString = Format(TimeNow, TIME_FORMAT)
    
    Dim srg As Range, crg As Range, cell As Range

        If Len(CStr(cell.Value)) > 0 Then ' Stamp
            BuildRange srg, cell
        Else ' Clear

    If Not srg Is Nothing Then
        With srg
