I noticed that the links I supplied to specific pages of the presentation did not open right up to the pages. You will have to click through the presentation to get these desired pages. I,m sorry for this, I tried to make it as easy as possible for anyone to follow along with my DD, but, I,m not a very good teacher and assumed these links would open directly to the pages I was referring to. Pages 11 and 12 should be the ones to look at , or better yet, look at them all to maybe get some other useful info, if you have time.
