[Qgis-user] Generate autofield

[Jose C. Rodríguez Durán]

Hi everybody,

I'm trying to generate an automatic field, I mean, a field that depends for
two others. We have FIELD1, FIELD2 and SUM. The result should be SUM =
FIELD1 + FIELD2. The thing is, if I change the value of FIELD1, the value
of SUM should change. Example: FIELD1 (8) + FIELD2 (10) = SUM (18)  ----->
FIELD1 (4) + FIELD2 (10) = SUM (14)


Any idea??

Thanks in advance for your help!!
