Sorry Arthur!
I really meant YOU!! I guess I just looked at the previous poster without considering that it might not have been you by the time I posted a reply... I'll try to do better next time. At any rate, your explanation was both well written and very instructive, as were YOUR pictures!!

Best Regards,
