Thank you for following the guidelines of discussion. Awesome! Hopefully the grade will be better than the first 2 discussions submitted. I was fearful when I received an email requesting to send a copy of the book. Please remember that I confirmed whether or not you all had access to the book before I submitted my first request for assistance.
