Answer 1

Here's a hint. Next time, post your answer. Say something like you followed along and did what the book said, but you just don't "get" how you arrived at the answer. That way everyone who is willing to help will actually help. Oh, and everyone IS truly willing to help. They're obvioulsy just not willing to be motivated for you...we're all lazy too.
