Hello again Orange,
It's great to know all of you are not babies I am more than pleased to have found this excellent forum. As little as I know about this subject, you all don't give me the sense I'm Dumb and that's very important to me. Plus, I feel OK to return and ask more questions. You all are top teachers/instructors who make it easy to ask questions about what we don't know. Thank you all so much for that.
