i am working with targets on my worksheet. how can i set a cell to change
its
colour according to the data entered. I.E. i set a target of 9% and i want
the cell to change colour to green when 9% or less is entered, if above 9%
i
want it to turn red, if within 10% of the target figure i want the cell to
turn yellow. is this possible?
