summing an array by product category

[Guest]

I need help writing a macro that will look down the first column and will add
up the prices of whatever rows that have the same category.

Example:
category product price
pets horse 100
pets dog 50
food banana .50
food hamburger 1.50

pets subtotal: 150
food subtotal: 2.00

Thank you very much.

Hi
It is possible to do this without a macro using SUMPRODUCT or SUMIF. If you
don't specifically need a macro, post back and we'll respond for you!

oTry a pivot table, it will give you this, in the layout drag the category
header in the row field and the price to the data field

Andy, I don't specifically need to use a macro so long as I can continually
select more products and the subtotals change with the new selection. In any
case, I would like to see how the two functions you described are use.
Thanks a lot

=SUMPRODUCT(--(A1:A100="pets"),C1:C100)

or

=SUMIF(A1:A100,"pets",C1:C100)
