I hate to sound like all the rest, but you have no idea how much you have helped all of us. I read alot of posts and one thing for sure is that ehroof would take his time and answer a question that has been asked millions of time before! How many of us can say we do the same. I read about your wife and will would like to say a prayer for you and yours if you have no objections to. Your knowledge is infinite!!! Take care and peace be with you!!
