Fred, I thank you for your interest, but you don't seem to be paying much attention to what I've said here. Your most recent question, for example, was previously answered clearly, as had been your questions in the post preceding that one (and which I answered again in my reply). As I told you, your original link was no help. Under these circumstances I don't have time to check out the seven new links you've posted.
