Examples
This example references the following sheet information:
Item  Quantity  Cost  Warehouse 

Shirt  26  20.00  A 
Pants  24  50.00  A 
Socks  10  10.00  A 
Shirt  18  25.00  B 
Pants  16  75.00  B 
Socks  46  15.00  B 
Given the table above, here are some examples of using SUMIFS in a sheet:
Formula  Description  Result 

=SUMIFS(Quantity:Quantity, Cost:Cost, >30,Warehouse:Warehouse,"A")  Sums the Quantity of any item from Warehouse "A" with a Cost over 30.00  24 
=SUMIFS(Quantity:Quantity, Quantity:Quantity, >10, Cost:Cost,<20)  Sums the Quantity of anything over 10 with a Cost under 20.00  46 
=SUMIFS(Cost:Cost, Quantity:Quantity, >15, Warehouse:Warehouse, "A", Item:Item, OR(@cell = "Shirt", @cell = "Socks"))  Sums the Cost of anything with a Quantity over 15 from Warehouse "A" where the Item is either "Shirt" or "Socks" NOTE: This formula also uses the OR Function and @cell parameter.
