I have a table where 1st column has the store names and the 1st row has items
(for some reason they are not unique). For example:

Sales RetailExpense StockLoss RetailExpense GrossMargin
Dahua 120 -5 -20 -12 20

Hebin 100 -15 -10 -12 16
HuZhou 130 -19 -10 -20 16
Wuxi 100 -29 -15 -17 18
Jinhua 160 -19 -10 -20 16

Then I have to create summaries by stores. I need a formula in each by-store
sheet to sum the numbers that meet both the row and the column conditions.
eg. a particular store (it's changing sheet by sheet but always has the name
in cell J1)'s total retail expenses.

I hope this is clear. Thanks.
