[LVL ED] Level Doors

[ZIEGMEBALLEN]

That's probably because you just renamed it, and didn't remove the last boolean parameter. This one only has 2 parameters, whereas the swing door has 3.

Remove the last true part.

Okay i removed the true part now, now it looks like this:
SetLevelDoorLocked("LevelDoor1", false,);
But it didn't worked
