Assuming the dates are real dates
=SUMPRODUCT(--(MONTH(E3:E276)=1),--(F3:F276="TRUE"))

If the TRUE is a Boolean true (and since it is in caps, it look as if it is)
then we can shorted formula to
=SUMPRODUCT(--(MONTH(E3:E276)=1),--(F3:F276))

Hi,
I've been trying for 2 days to make this formula work. I have a
spreadsheet
that shows the employees that have been hired and the ones that have left
the
company. I need to count how many have arrived for each month.
Column E has the date and Column F has the status (True for arrivals and
False for departures).
I need to have a formula that would combine:
=COUNTIF(E3:E276, "TRUE")
and
=COUNTIF(E3:E276, "2007-01-*") (I'm not sure about the use of the wildcard
in a formula)
Any help would be greatly appreciated
Thanks
Jeanne
