You could have a formula in C2 =IF(A2="no", "Be sure to fill in B2","")
Or you could have event code that popped up a message.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Intersect(Target, Me.Range("A2")) Is Nothing Then Exit Sub
On Error GoTo CleanUp
Application.EnableEvents = False
With Target
If .Value = "no" Then
MsgBox "Please fill in cell B2"
End If
End With
CleanUp:
Application.EnableEvents = True
End Sub
Note......both of these are reminders only and if users choose to ignore the
messages or disable macros.................then what?
