Hall Lighting - two way switch

[scally58]

I think I have really messed up, i'm so confused I don't know what my name is or where I live..............Here goes.

I have a double swith both downstairs and up stairs, the downstairs switch has 3 cables going to it, all red, black and earth. I think one is the Live as this has the only current going to it and I guess the other two are for the lights, where should all these go in the back of a two gang switch?

Up stairs there is another two gang switch, behind the switch I have coming from I think downstairs 1 red which I think is the live, 2 yellow, 2 blue and 2 red. I also have coming from above 2 red, I cant see what cables all these are coming from. After 10 hours of trying to work out what goes where i'm stumped. yesterday I had a combination where all the bedroom lights were going off when I switch off the hall lights.

What goes where? common, L1, L2

Or should I get an experienced electrician?
