Runningsum results appear blank

Hi Andy, thank you for the workaround and the explanation. I am seeing the same issue. but my calculated field {numerator} ({balance} from above question) is a distinct_countIf({engagement_id}, condition1 AND condition2 …).
I did the ifelse, that works fine. named this field {numerator_c}
but when I try to do sum({numerator_c}), I get error:
“Nesting of aggregate functions like runningSum and RUNNINGSUM(SUM(CASE WHEN COUNT(DISTINCT CASE WHEN condition1 AND condition2 … is not allowed”

Thoughts on how to resolve this?
