So, your contention has boiled down to the fact that you disagree with the notation, despite the fact that earlier you seemed to have no problem understanding it? Can you walk away for a few minutes from spending so much time and effort in proving me wrong and help Pete with his misunderstanding? It is a very simple issue but 100+ posts on this subject and he still fails to see it. THIS is what he really, really needs help with. Can you spare some time and help him?
