Layer A - SOVEREIGNT, Field2, Field3, ...
Layer B - Country_Region, Confirmed, ...
I want to aggregate the Confirmed field of Layer B into Layer A.
I try to create a virtual field in Layer A with the _expression_
aggregate( 'B','sum', "Confirmed", "Country_Region" ILIKE attribute($currentfeature, 'SOVEREIGNT'))
but the value is always zero.
What am I not understanding?
Thanks
David
