No problem. glad to help. The "(--" turns Excels logical values True and
False into 1's and 0's respectively. The 1's and 0's get multiplied by their
corresponding results and then everything gets added. All the items that had
0's do not show up because 0 multiplied by anything = 0.

try the following web-site:

On the first sheet (the one with name - column A, product category - column
B, and product - column C) place the following formula in column D to get
sales.

=SUMPRODUCT(--(Sheet5!$A$2:$A$4=$C2),Sheet5!$B$2:$B$4)
Where Sheet 5 is where you have your other information (Product - column a,
Sales - column b, and cost - column c).

The below formula will you get you cost.
=SUMPRODUCT(--(Sheet5!$A$2:$A$4=$C2),Sheet5!$C$2:$C$4)

Hope this helps.

Hi,

I have two worksheets, first one with "name", "product category", and
"product", second one with "product" (sames as the first sheet product),
"sales", "cost".

How can I sum up the "sales" and "cost" by the "product category" with the
least effort. (VB is not allowed :)
