Somewhat confused by your question... suspect you are attempting to wire an external light to be controlled by two switches - one indoors and one outdoors...
This link may help... second picture is easier to understand...

LIVE needs to pass through both switches for the lamp to illuminate so that either switch may interrupt the supply. Live in to one switch - two paths for live to travel to second switch - one path from second switch to the lamp the other side of which connects to Neutral.
There should be no "neutrals" connected to either of the switches.
New Euro wiring has Brown for Live and Blue for Neutral.
Good luck...Take care...
