I have a spreadsheet where we input a date when we had first communication
with a potential parent/student. I want the cell to change colors when 10
days have past with no contact. In other words I want to be "alerted" when
we did not follow up with a potential client. Please explain like you are
talking to a second grader because I am a novice user, but I can get it done
if given good directions.

Many thanks!
