Vba and Fomula conflict

Hi and thanks for taking the time to read my Post

You guys have been a Great Help so far

ok i have this code on sheet4 "HIDE" works great, but when i put a fomula =PLAYERS!B19 in D2 and =PLAYERS!C19 in E2 on
sheet4 "HIDE" the VBA code doesn't work, is there a way to make them both work?

Private Sub worksheet_Change(ByVal Target As Range)

    If Target.Count = 1 And Not Intersect(Target, Range("D2:E21")) Is Nothing Then
    Application.EnableEvents = False
    Target.Offset(0, -2).Value = Target.Value + Target.Offset(0, -2).Value
    End If
    Application.EnableEvents = True
    
End Sub

Thanks
Keith
