Cumulative Sum of Specific Values

[az1234]

Hello, I am new to Qlik and would appreciate any help!

I am trying to sum values within a month to get a MTD formula, except my data is not in that format. As an example for July I have this formula:

Aggr(RangeSum(Above(Sum([Total Revenue]),0,RowNo())),({$<Year=2019>}) +({<[Month.Week]="7.1","7.2","7.3","7.4","7.5"}>}))

I am hoping to have Week 1 of July, then Week 1 of July + Week 2 of July, then Week 1 of July + Week 2 of July + Week 3 of July, and so on. And then to extend formula with other months.
