Lever isn't working?

[Amnesiaplayer]

My lever doesn't work, somehow.
I thought this may be another "problem" since the lever isn't full at begin. you have to attach the lever to the mount. after doing that, Lever and Mount are Deactivated, and the FullLever is activated.
So now, I tried this :

PHP Code: (Select All)

SetEntityConnectionStateChangeCallback("FullLever", "MoveWall");

void MoveWall(string &in asEntity, int alState)
{
     if (alState == 1)
     {
     SetMoveObjectState("Wall",1.0f);
     PlaySoundAtEntity("", "quest_completed.snt", "MoveWall", 0, false);
          return;
     }
} 


But it doesn't work, I know the Wall wouldn't work, but the sound also don't start.
I tried some other things. but nope, to make sure, the FullLever doesn't have anything filled in Entity tab.
And about the wall, It's just a custom Plane. I think this can't move unless you make an entity of it, and make it moveobjectstate right?! because I need this wall to move. not that already made castle one.
