问题 I want to have script based formatting to color code date columns. Row 1 is labels. Cols C-E contain dates;these are the cells I want to color format per date. I'm starting with Yellow in the conditional and will add more colors once I'm paste this hurdle. The hope is to check each cell and color it appropriately.
