How to do cumulation in KPI

[krishna_thaker]

Can someone please tell me what is wrong with below formula:

Rangesum(Above(TOTAL count({<[Date Type]={'Registration'},
Registration_Date={">=$(=Date(AddMonths(2022-08-15, -1), 'YYYY-MM-DD')) <= $(=Date(Max([Canonical Date]), 'YYYY-MM-DD'))"}>}distinct [User.Id]), 0, RowNo(Total)))

I am trying to calculate total registered used based on Registration Date.. where it should show total users till max date selected and min date would be the very start date.

Thanks,

Krishna
