I have this visual basic code in my spreadsheet.

Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
If Target.Address = "$G$10" Then _
Target.Offset(, 2) = Target.Offset(, -2) * Target * (-1)
If Target.Address = "$I$2" Then _
Target.Offset(, -2) = Target / Target.Offset(, -4) * (-1)
Application.EnableEvents = True

If Target.Row < 2 Then Exit Sub
Application.EnableEvents = False
If Target.Column = 7 Then _
Target.Offset(, 2) = Target.Offset(, -2) * Target * (-1)
If Target.Column = 9 Then _
Target.Offset(, -2) = Target / Target.Offset(, -4) * (-1)
Application.EnableEvents = True
End Sub

It worked fine, but suddenly it stopped.
How can I make it work again?
