[Qgis-user] Help in Field Calculator

[Daniel Alejandro Montecinos Rubilar]

Hi. I have a question urgent. What I try to do is then updated columns in a data layer with another layer. For example , I have two layers A = Poligono , B = Points . The layer B contains real values. Then would do two things. 1. Count how many points of the layers B are within the layer A. 2. From the points of the layer B that are within the polygon layer A, I need the sum of their values ​​and paste this sum in a column of created layer A. I tried to make the crossing with the "field calculator" function, using the functions: "geomwithim", "geomintersects" and "intersecting_geom_sum", but without results.

 

I hope I have been able to explain.

 

Greetings and thanks for your support.
