Calculate on exit of combo box

[Tony Miall]

Hi all,

Just starting out with user forms and I would like the sheet to calculate when the user exits a combo box after entering a value and moves to the next one . I've tried a few things like

Private Sub State_AfterUpdate()

    If STDORDERFORMENTRY.State.Value <> "" Then
        Sheets("STD ORDER").Calculate
    End If
  
End Sub

but cant get it to happen.

any help appreciated as usual
