Thank you! I think maybe I am getting part of the issue solved. I followed directions on one tutorial where it told me to drag the exterior hip walls in towards the middle (long walls) on the second story to create the "room" upstairs. That did not work at all. I now have deleted the second floor and started over using a different tutorial. So far, I think I have solved my problem as I now am able to draw the interior walls and click on the rooms including the attic space and label them. Hopefully, now I can add the addition and the 2nd story. I will be back if this does not work. Thank you!
