I have a worksheet that I need to run a macro on where, if certain
cells are blank, then I want to color them yellow. They all start out
pink (required input). I want to then run the macro again and if any
of the yellow cells has then had input put in, then it needs to be
changed back to pink, and any pink cells that no longer have data in
them, need to be turned to yellow.

Any clues?
