Lighting

[lisamartine]

I am trying to put some lights on a patio. I put the light fixture in place, then 3D-Add Lights and place the lights inside the light fixture. When I go to view this and toggle the sunlight there is no light at all - do I need to do something else. i've tried from putside the patio room and inside the patio room and it makes no difference it isn't there!
