I have random date ranges over the month break, but I need to get a day
count
by month to calculate rev by month.
Eg:
Range: 10/15/06-12/31/06 I need to know # of days in Oct, Nov, Dec from
that
range.

Was going to set up one column/month to then put the result into a formula
to figure (total rev for deal / # days in deal)*# of days in deal in that
month=revenue for month

Hope that makes sense.
Any help?
thanks in advance,
