So I want this if statement and the nect color in the pattern to be added in a new row below it, it adds the black and check boxes but, not the if statement and it just copies the color above how can I have it do this automatically? (the color pattern is a simple grey white to help differentiate visually)
I heard it should auto add formulas if theres enough above it but I have 8 rows with this statement and if thats not enough to auto add idk what is.
