Thanks cedarS THAT means a lot to me. Perna, you amaze me with your links. I found the link and it's link so informative. I am not crazy, that is why people act like I have a green head. CedarS. You could identify with all of it? Can you explain more? I want to understand more for my own self so maybe different words gives me a different angle to understand through? Anway, thanks guys.
