=SUMPRODUCT(--(J2:J100="neg"),--(L2:L100="neg"),--(C2:C100=False))

TRUE and FALSE... Here is a link to sumproduct which will give you some
insight into how it works...(bookmark this one)

I am tyring to count the number of individuals who match certain criteria

but it didn't work for me. I'm obviously doing something wrong!
