we replaced most of the knob and tube in the attic and some of the walls recently. i am updating the light switches now.

in my hallway, i had 2 switches in a box: one controlled the hallway light and one controlled the patio light. there are 3 wires in the wall. the wires were too short so i am moving the box up. i picked up a Leviton 5224 switch - combination 2 switches (two black common screws w/ a ground on one side and two brass (A1 / B1) on the other.
can anyone help with the wiring? we couldn't get it to work properly. i have kept the tab in for now to keep the two switches connected.
