I installed a one outlet gfi with a switch, it replaces an old two wire receptecal, the lightb switch works but the gfi will not reset, keep in mind it only has two wires coming from the power source, how do I hook up the two wires that are on the new recptecal along with the power source wires?

The hot black connects to the LINE brass screw of the GFI, the white neutral connects to the Line silver screw.
