two switches on the same light. one cable has three wire 1 red 1 black 1 white, the other one has 2 cables but only 1 white 1 black and another black which loops back in the box. I removed old switches and there was no marks on them for common wire. I'm trying to install new switches with no joy. Any hints

Your post is confusing. I think you used the words two cables and instead meaning one cable with one blck and one white conductor in that cable. I see a flag showing when you said that you have a black looping in the box without leaving the box also.

It sounds like you have a 12/2 power in and a 12/2 power out with a pigtail going to what we call the common screw of the switch.

Can you tell us what colors are on the screws of the switch and how many cables enter the box, whether it is a single or double, etc. and whether these cables are 12/3s with black white red or 12/2 with black white only. We take for granted you have bare conductors in these cables also.

Then discribe the second switch box the same way. Then we can help you sort out the wiring pattern that you have and where to advise you to connect the conductors.

We are Watching for your repost.
