I need help creating a sumproduct formula to sum the sales data for a
particular sales territory. The data sheet that the formula will
reference is set up such that the column headings are in row 28 and the
data begins in row 29 (I won't bore you with why) and continues on for
thousands of rows. The columns a Brand, Territory, Product, Sales1
(sales for current month), Sales 2 (sales for last month), Sales
3,....,Sales 24.

On the summary sheet where I will place this this sumproduct formula in
cell B10. I have in cells B1:B4 the values I am looking for that I can
change and the formula in cell B10 should then update:
B1 = Brand in question
B2 = Territory in question
B3 = Product in question
B4 = # of sales months to sum.

B4 is a wrinkle because the # of columns of data for the sumproduct
formula to sum is variable.

I am guessing that some combination of dynamic ranges and a sumproduct
formula maybe could accomplish this. How can I make this happen? Any
advice would be greatly appreciated.
