range sum question

[ali_hijazi]

Dears

got a pivot table and 4 expressions grouped by period and release

what I want for the fourth expression is cummulative summation by release

i.e.

check the image; for release v3.1.27 on period 2 I want the value of 89 (21+68)

I wrote the following expression

$(vBackportedBugPostRelease) + $(vBackportedRegressionPostRelease)

+ rangesum(above (total $(vBackportedBugPostRelease) + $(vBackportedRegressionPostRelease),1  , RowNo(TOTAL)))

but I'm getting the value of 101 (summing the remaining records that have 5,5,1, and 1 as values

Please advise
