How to get total field with auto increment

[Anonymous]

Hi,

I have a source

Product	Price
A	100
B	250
C	150

But i want to display with extra column like this

Product	Price	Total
A	100	100
B	250	350
C	150	500

How can I get total field by auto increment.

Hey Amar

Use this

aggr( rangesum(above( sum(Price), 0, rowno() )), Price)
