Let's say I have two layers with the following attributes:<br>
Layer A - SOVEREIGNT, Field2, Field3, ...<br>
Layer B - Country_Region, Confirmed, ...<br>
<br>
I want to aggregate the Confirmed field of Layer B into Layer A. <br>
I try to create a virtual field in Layer A with the expression<br>
aggregate( 'B','sum', "Confirmed", "Country_Region" ILIKE
attribute($currentfeature, 'SOVEREIGNT'))<br>
but the value is always zero. <br>
<br>
What am I not understanding?<br>
Thanks<br>
