Problem with my light switch how to rewire it please?

I have a switch in my hallway with three light switches.Left hand switch is for the hallway light,there is also another switch at the end of the hall for the hallway light.The middle switch is for the porch light and the right switch is for the outside light. The wiring for the hall switch has a red,blue,earth and a plain yellow.The porch wiring is the same,the outside light has a red blue and earth only.The hall and porch red cables are live and a bridge cable from one of them supplies power to the outside light. Each switch has a com L1 & L2.I can get the hall light to work on the left hand switch but it does nothing on the other switch at the end of the hall.What is the correct way to rewire this please,tried a sparky but they don't want to know,5 minute job for them I suppose.Thanks in advance.

Make sure the wire that feeds the outside light is coming from the switch for the porch light, not the hallway light.
Wire the switch at theother end of the hallway the same (eg Red - L1, Blue - L2, COM - Yellow).
There should also be a red and black wire; these also go to L1 and L2 (doesn't matter which).
