I have a sheet of percentages in columns where each cell is already populated with a formula. I want to format the font of each cell in a column based on whether it is greater or less than the previous cell, i.e. If B4>B3 make it green, if it's less make it red. Google has given me nothing but formatting based on fixed values, not 'whatever cell x contains' so am at a bit of a loss.
