The double negative converts TRUE/FALSE to 1/0. The reason it doesn't work
without them is Excel doesn't understand a summation of TRUE's and FALSE's.
You can also achieve this by doing any kind of mathematical computation to
the ranges, for example both of these will work as well:
=SUMPRODUCT(1*(L10:L93="Tabriz"),1*(E10:E93="A"))
=SUMPRODUCT((L10:L93="Tabriz")*(E10:E93="A"))
You can learn more about SUMPRODUCT() he

Hi David,
This is something I need to learn.
Why does it work with the --?
Isn't that like a double negative? Why doesn't it work without it?
Where can I find out more about this?
thanks for your help

Column E: class of doctors. Includes A,B,C
Column L: residing city of doctors
I want to count number of doctors with class A in a specified city.
I thought the following formula will work:
IF(L10:L93="Tabriz",COUNTIF(E10:E93,"A"),) but it didn't.
Basically I am looking for a foormula to count a cloumn when a condition is
met in another column.
How can I write this formula?
