One way, if you put the start and end dates in say N1 and N2.

=SUMPRODUCT(--(Sheet1!B1:B100="John
Doe"),--(Sheet1!C1:C100="sick"),--(A1:A100=N1),--(A1:A100<=N2))

I have a spred sheet tracking absenteeism using the following formula
=sumproduct(--('sheet1'!B1:B100="John Doe"),--('sheet1'!C1:C100="sick"))
each time John Doe is sick it displays on sheet 2
in column A is the dates - ------ I wish to track it Quarterly --- is it
possible to add a third criteria so it will track from (Jan. 01/09 to
March
31/09) (April 01/09 to June 30/09 ) etc. I would prefer to use dates if
possible
