In this diagram power enters the fixture box. All the white wires are capped together and the same is for the ground wires. The black wire from the other 3 way gets connected to the line black wire.

Push the switch into the box and secure it with screws at the top and bottom. The black hot wire connects to the far right switch s common terminal. Turn on the power and test the switch.
