I'm simply trying to add values in a third column if the
values in the 1st two columns meet my demands.
a b c
bob mary 10
bob susy 9
mark jan 15
steve bambi 12
jon carly 8
bob mary 27
I want to ask for a total of column c where a=bob AND
b=mary. In this case, the answer would be 37.
PLEASE - how can I do this?
