I have a column of starting dates with a second column of dates 60 days after
first, in a third column I have a event date. I need to count row if event
happens within the 60 days of first column.
10/15/09 12/14/09 12/1/09 1
10/15/09 12/14/09 12/15/09 0
10/25/09 12/24/09 11/15/09 1
10/13/09 12/22/09 11/1/09 1

Thank you
