Did anyone find out why the bathroom and closet lights stop working?

If you tried to reply to a thread it didn't work, you started a new thread.

Can you explain your problem?

I changed the switches in my closet and ensuite bathroom now the lights will not come on. I also changed the light in the bedroom but that one works.

Well, you wired something wrong. Not much to go on here so that's the best I can do.

Turns out that of the three wires in the box non were ground so when I attached one to the ground on the switch it caused the bath and closet lights to not turn on. All fixed.

The grounds have nothing to do with the working of the circuit. If you connected or disconnected one and it fixed things something is seriously wrong still.
