It has to be snapped to the floor and be tied to an info_landmark. Are you in NAV mode when you test it? (Is the bright blue text showing up in the console when you're in the SR and the door is closed saying "Would change level... but not going to!" ?)
Ok, Nav flow now works!
But one question: How do you make a setup where there are 5 button press events leading up to the opening of 2 doors?
Example: Press 5 buttons in any order and then something happens.EDIT:
Nevermind, I got it using the mathcounter.
