When using the SUMIF function You have a look-up range,criteria and
sum-range. How can you specify two criteria in two look-up ranges. i.e.
Colomn A1:A100 are sales reps, B1:B100 are products sold and C1:C100 is Price
of sale. So add up all pots sold by Julie. Therefore criteria in A:A is Julie
and in B:B is "Pots" and then add up C:C. What does that formula look like?
