Auto unique numbering
I want a unique number automatically inserted using the Worksheet_Change event. When a cell in column D contains a value column E will automatically display a unique 13 digit number which is incremented by one. The worksheet will be sorted regularly, so taking away the worry of knowing what the last number used to avoid duplicates is vital. Anyone got the know-how on this? Many thanks! Pat |

Auto unique numbering
Hi
try Private Sub Worksheet_Change(ByVal Target As Range) Dim counter If Target.Cells.Count 1 Then Exit Sub If Target.Column < 4 Then Exit Sub On Error GoTo errhandler Application.EnableEvents = False With Target If .Value = "" Then .Offset(0, 1).ClearContents Else counter = Application.WorksheetFunction.Max(Me.Range("E:E")) + 1 .Offset(0, 1).NumberFormat = "0000000000000" .Offset(0, 1).Value = counter End If End With errhandler: Application.EnableEvents = True End Sub -- Regards Frank Kabel Frankfurt, Germany Pat wrote: I want a unique number automatically inserted using the Worksheet_Change event.

Auto unique numbering
Hi Frank,
Your code worked beautifully. The only thing I need cleared up is if the Offset is change as follows: .Offset(0, 5).ClearContents Else counter = Application.WorksheetFunction.Max(Me.Range("E:E")) + 1 .Offset(0, 5).NumberFormat = "0000000000000" .Offset(0, 5).Value = counter incrementing does not take place, why would that be?

Hi
you're inserting the values in column I?. If yes change the line counter = Application.WorksheetFunction.Max(Me.Range("E:E")) + 1 to counter = Application.WorksheetFunction.Max(Me.Range("I:I")) + 1 -- Regards Frank Kabel Frankfurt, Germany Pat wrote: Hi Frank, Your code worked beautifully.
