Count using complex criteria

[Rob]

Hi,

Hopefully the table below shows, copied from Excel.

I need to count the number of live contracts at a given date, a contractor
can have several contract entries, for example Jones (459) had a contract
from 10/02/99 to 12/05/04 but also renewed his contract from the 13/05/04,
for Jones I would want to count him once as he was live at the month end:
30/04/05. Joyce (850) has 3 entries and his termination date is after the
month end of 30/04/05 so again I would count him once from the second entry,
the third entry of Joyce is a future renewal which starts after the month
end so wouldn't be counted.

Can this be achieved with a single formula?

Thanks, Rob

Live contracts:
Tern contracts:

Try this formula:

=SUM((C2:C13<=$H$2)*(IF(D213>0,D213>=$H$3,1)))

(array entered, i.e. with ctrl+shift+ enter, instead of enter)

The hypothesis is that your table is in the range A113, with headers in
the first row, so in C2:C13 you have start dates and in D213 you have end
dates.

Hoping to be helpful...

Thanks very much Franz, that has got me started, with a few tweaks I'll be
there - I hope!
