Is it possible to add another dimension to the instances per date,
can a
filter of another column with citeria of say "Airbus"
Start End Fleet
1/1/2009 1/2/2009 767
1/1/2009 1/3/2009 Airbus
1/1/2009 1/6/2009 767
1/1/2009 1/5/2009 Airbus
1/1/2009 1/3/2009 Airbus

So I'd like to filter on "Airbus" using the
SUMPRODUCT(--(Sheet1!$A$1:$A$10<=A1),--(Sheet1!$B$1:$B$10=A1))

I have a start and end date on one sheet, another sheet with a list
of
dates
in the month.
I need to know how many instances the item was active on a given
date
such as
1/1/09 - 5
1/3/09 - 4
1/6/09 - 1
Start End
1/1/2009 1/2/2009
1/1/2009 1/3/2009
1/1/2009 1/6/2009
1/1/2009 1/5/2009
1/1/2009 1/3/2009

Thanks Bernie
