I am trying to install a new combination switch, single pole/3

Resolved Question:

I am trying to install a new combination switch, single pole/3 way. One switch, 2 separate circuits. The swithes I'm replacing were orig to house (55 yrs). Well, single pole is fine. The 3 way worked fine then it went funky; the primary (comb switch) would turn te lights on & off but the secondary switch won't do anything. Then the secondary would work OK buth the primary won,t. At that point, I changed the secondary switch; NOW nothing works.

Help....

This primary seconderry you are talking about is this the 2 switches ?

Can you open up the light and tell me what color wires are going to the bulb ?

The primary switch is the combo; single pole is fine.
The secondary is the end of the 3 way run.

Sorry! Getting to the light wiring means more work than I can do tonight. What if they are black?
Expert:  Glenn replied 7 years ago.
I would first put the black on both silver screws of both switches don't worry about the red and whites but hook them up

Wires are black to each bulb. changed the black wire to silver screw
and red to brass. NOTHING   Set up as of now
#1 switch (primary)BRASS SCREW=RED ON TOP;WHITE ON BOTTOM
