I could not solve this case, any help?

[tincholiver]

Hello team, I was trying to solve this case but I can not achieve it:

https://community.qlik.com/t5/QlikView-App-Development/Intervals-entry-output/m-p/1559283#M441136

The last two columns accumulate values but I could not solve it with the aggr function, in turn there are null values that I can not solve with the formulas I am applying.
Attachment qvw with the advances, I appreciate your advice!
