Trigger on/off not working

Hello :)
I got this trigger (realy basic one) wich senses a units aproach

event- unit comes within X range of unit
Conditions-
actions- ping triggering unit's location

so far so good.


But i have a trigger to disable it if they ever find it bothering
Event- Player types exactly -sense off
Conditions-
Actions- Disable (the trigger above)

For somer reason that doesnt seem to work... any ideas why

you need an event for each player that is

Player chat message = -sense off

What he means is, make sure that the player who's typing the message is the one for which the event is registered.
