I have a sumif formula counting a rolling 6 month period that is summing
total points only accumulated in that 6 months.  I'd like to add conditional
formatting that will only change the color if that particular instance of
earning points is being counted in the sumif formula.  I also wanted it to
change different colors based on if the particular instance pushed the total
points to equal to or greater than 4, 6 and 8.

So I'm trying to add the conditions to column C (which is dates of a
particular instance) based on whether or not that date is counted in the
total Points in column B (where the sumif formula is located).
