But the catch is I already have 1 light working with power in and power continuing to other lights and switches. I want to add 1 more light and 1 switch to control these 2 lights. PLEASE HELP. THANKS

If you are already wired up with one switch and a few lights you can add more lights but you can't just add a second switch. A second switch consitutes a 3 way, both switches must be 3 way switchs and you need more wires for a traveler
