checkpoint 2 was much easier than checkpoint 1. It was intersting that maximum does not really include the maximum number I intended to have, so I revised maximum by adding plus 1, and this allowed me to have the maximum number I planned to have in outcome page. I did not feel I was struggling with checkpoint 2, I am still processing checkpoint 1 question though.
