Hi,

I've a bunch of features relative to adresses and associated inhabitants.

I've already grouped the features by similar street names and numbers wich results in the "match_id" column.

What I need now is to sum each four "total..." column's value (separately) by using the "match_id" as grouping value.

The goal is to get the number of peoples, etc ..., living at one adress.

I've tried several transformers after the AttibuteManager but none return the attented values.

Thanks for your help
