Running Balance in Cell Needs To Be Highlighted (reverse process)

RE: Excel '10 Problem

Hello,

On the Excel sheet I'm working on (see image from this TinyPic link: http://tinypic.com/view.php?pic=2ep7koz&s=8), I’m trying to get the most recent (running) balance to appear in a blue-highlighted cell with white text. In this case as you see, this is cell H11 (white text, blue background). And, as the balance runs down on the page, I would like the highlighting to VANISH in the previous cell (H11), reverting to black text, white background and then highlighting the next cell down (H12) in the same manner, with blue background, white text . . . in this fashion all the way down the page (with the most recent balance highlighted in blue with white text). Does Excel '10 have the ability to do this, or is this type of thing beyond the formulation parameters of Excel '10?

Thanks so much for anyone's input.
