I am trying to evaluate three attribute fields and return a different value. When I try this expression I get no return.
CASE WHEN (Att_A =1) AND (Att_B = 2) AND (Att_C = 3) THEN 40 END
When I try it with 2 I get a return.
CASE WHEN (Att_B = 2) AND (Att_C = 3) THEN 40 END
Can you not evaluate three items in a case statement in QGIS or am I doing something wrong?
