No Duplicates

[Guest]

I have a table with ITEM_NO as the indexed field - with no duplicates. I have a form set up so that new items can be set up. The table's name is tblITEM. Will someone show me how to write a code that will clear the ITEM_NO field and reset the focus if they key in a duplicate item number? I'm sure it is easy, but I can't figure it out. I'd also like to have an error message indicating the duplicate number appear. I'd appreciate any help. Thanks..

violating a field's unique index in the form's underlying table
automatically causes a form-level error. in the form's OnError event, add an
event procedure to trap and handle the error, as

Private Sub Form_Error(DataErr As Integer, Response As Integer)

If DataErr = 3022 Then
Response = acDataErrContinue
With Me!ITEM_NO
MsgBox .Value & " is already being used. Enter another " _
& "item number, please."
.Value = Null
.SetFocus
End With
End If

End Sub

recommend you read the OnError Property topic and the Error Event topic in
Access Help, so you'll understand how the code works.
