I thought this was pretty straight forward but I guess not. I have a cell that I want to alternate colors between green and red depending on another cell being > or < a third cell. For example I want A7 green if B8>=A8 and red if B8<A8. I've tried the Formula Rule Type with A7 highlighted, $B$8>=$A$8 then format fill green and a second rule with $B$8<$A$8 then format fill green but it doesn't work. It always stays green in each criteria.
