I have a GFCI outlet with a switch on top. The switch goes to overhead lights. The instructions that come with the GFCI are confusing. I have installed GFCI outlets before. The unist has two wire leads that I think are supposed to connect to the black and white wires leading to the lights. When I wire according to what the instructions say my outlet works fine, but the switch will not turn on the lights. If I wire the two wires leading to the light into the load part of the outlet the lights come on and stay on. The switch will not work in that case. Please help.
