I've posted this before but see post 'have i bought the wrong switches'
i have now reconfigured the wiring. to summarise i have a main light (2 way single) switch next to my door and a wall switch (two way double) which controls the main light from another location and also a completely seperate set of light. I will describe how everything is wired below .Everything works ok apart from the fact that when the main switch is on and therefore the main light is on; the switch which should switch it off/on (on the double switch) does not work. as a point to note if the main switch is off the secondary switch on the double switch does switch the main light on/off with no problems. fyi the other switch on the double controls a wall light which works as it should. to summarise i need to be able to switch the main light on and off from the double switch when the light is already switched on at the main.
heres the wiring at the main single switch which controls the main bedroom light
