Hi, I'm Mike and I'll be assisting you. Please stand by while I review your question.
You have a single pole switch and not a 3 way. Return it. When you get a new one the placement of the wires has to be the same for a 3 way operation. The wire on the black screw is the common and needs to be the same on the new switch.
LeBron is fine. Look at the back of the old switch for markings indicating common. That will be the wire on the black screw.
No, you may have an ungrounded switch. The other insulated wires connect to the gold screws and the ground to a green screw on the new switch.
Anytime, You're welcome.
