Dont allow blank

[nowfal]

Hi,
I would like to know how can i prevent a cell being blank. It i
like as follows:
I have colomn I,J,K,L . If colomn I is blank J,K,L should not take an
data, otherwise a message should come like you cannot keep the the cel
blank like that. Is it possible to do so. Any suggestion will be highl
helpful.
thank you

Hi
only possible with VBA using an event procedure before closing/saving
the file

You can use this event in a worksheet module

Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Cells(Target.Row, 1) _
.Range("J1,K1,L1"), Target) Is Nothing Then
If Cells(Target.Row, "I") = "" Then
MsgBox " sorry the I column is empty"
Application.EnableEvents = False
Target.Value = ""
Application.EnableEvents = True
End If
End If
End Sub
