Hi all,

I use a list where people add data in.

In column A from the worksheet "data" they add a code.

I would like that excel checks if that code exists in a range of existing codes that is on the sheet "products) in column A.
If it's a "new" code i would like to open a userform.

Anyone knows how i should do that?
 

Excel Facts

Which came first: VisiCalc or Lotus 1-2-3?
Dan Bricklin and Bob Frankston debuted VisiCalc in 1979 as a Visible Calculator. Lotus 1-2-3 debuted in the early 1980's, from Mitch Kapor.
How about
Code:
Private Sub Worksheet_Change(ByVal Target As Range)
   Dim Fnd As Range
   
   If Target.CountLarge > 1 Then Exit Sub
   If Target.Value = "" Then Exit Sub
   If Target.Column = 1 Then
      Set Fnd = Sheets("Products").Range("A:A").Find(Target.Value, , , xlWhole, , , False, , False)
      If Fnd Is Nothing Then userform1.Show
   End If
End Sub
