Paul, thank you for your response. We will definitely be reading the article you attached. I have read these to my husband, Jimmy and he was very happy that I took the time to ask the questions. I am grateful, like I told Christine, that you also ahve taken the time to speak with me. Your knowledge is very useful to us as well as many others. Thank you again.
