Need assistance in finding the df within for ANOVA testing.

For the df within I subtracted 8 from 8, but that gives me 0 which cannot be right because I would end up getting a Divided by 0 error for the MS within and the F. Can someone please explain how I may solve this? All I need is assistance with that part and I can solve the rest. I appreciate anyone that helps.
