Consider the formulae =SUMPRODUCT(--(A1:A10="Luke Skywalker"),--(B1:B10="West"),D1:D10)

What does -- mean in front of --(A1:A10="Luke Skywalker")
and --(B1:B10="West")

-- changes TRUE to 1 and FALSE to 0 so that SUMPRODUCT can calculate the
values. You can see it if you select a cell with that formula and choose
Formula = Formula auditing
