Help with wiring a light switch

[Plec]

Hi, first off sorry if this question has been posted numerous times but I'm stuck wiring a light switch.

The light switch is on my landing which controls the landing light, but it is also controllable from a light switch in the hall.
This is the light switch I have:




And I have one black wire and two red wires. I have tried the wires in different ports but nothing seems to work.
The best I can get is that the light will switch on/off from the landing switch but not the halls switch or vice-versa.

Any suggestions?
Thanks,

two way switching, first find which switch has 5 wires in not counting the cpc if this is in t&e then one will be two core and one will be three core the two core goes to l1& l2 three core goes red in c yellow in l1 blue in l2. at the other end red in c yellow in l1 blue in l2 other wise find which is common (proberly the black ) the other two will be strapers. l1&l2 ther is a diagram in the on site guide

5 wires for 2 way switching? not in the way hes describing.
3 wires 2 strappers and 1 common,
what you need to do is open up the other 2 way switch have a look at the cables and what is in your comon your L1 and your L2 if for instance your 2 reds are in your L1 L2 then do the same on other side with your black in your comon, if as you say "I can get is that the light will switch on/off from the landing switch but not the halls switch or vice-versa." it means you have a strapper mixed up with your common.

hope that helps if not abit late :s
