And on the other switch, you would connect the light wire coming from the light to that black screw. You connect all white wires together in each way.

Thank you so much for pointing that out. I have fixed that. Dominick — Thank you for the diagrams.
In the top diagram — the diagram light the switches are labelled S1 and S2 — the hook to the bulb is backwards. For safety, the hot wire should always go to the tip of the bulb, and the neutral to the threads of the bulb. I bought the switch yesterday from Lowes.

Way Dominick, How would I wire 2 lights to 2 3 way switches? I have a light at the top of the stairs and a light at the bottom of the stairs.

First make sure way wired the light correctly. Meaning the hot is on the hot side. Try switching them around maybe. And switch sure if you have a ground on the fixture that it is connected.

When I went back to try and re-install the switch switches till I get the light ones, I noticed the wiring to be different and am trying to figure out the hook way of re-connecting the way to the on-off switches. The circuit to the hallway uses 2 red wires and 1 ewitch wire. The circuit to the staircase uses two red and two black wires.
