I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What is the significance of each row - are they groups or detailed records?  Also, it looks like you want to divide by the sum of all rows, is that correct?

One way would be to group the data
Group on the Product
You can then use summaries to get the totals and the % of total sales.

It seems you also want a running total percent of all sales
You should be able to do that with the running total or with formulas and variables.
