Group of lights with area

Hi, I created a light group on configuration.yaml, only the code is incorrect if I put “area_id:” how can I put it?
ATTENTION, when the group is switched on or off inside the areas you must call up only the lights and not buttons and more inside the area.

    name: accendi/spegni luci
