[SCRIPT] 1 error which I can't solve/find?!

[FlawlessHappiness]

Are you sure you updated your script?

void Puzzle (string &in asEntity, int LeverState
{
if(GetLeverState("Lever1") == -1
&& GetLeverState("Lever2" ) == 1)
&& GetLeverState("Lever3" ) == -1
&& GetLeverState("Lever4" ) == -1
}

Also this:

void UnlockDoor(string &in asEntity, int LeverState)
SetSwingDoorLocked("Door", false, true);
PlaySoundAtEntity("", "door_safety_open.ogg", "Door", 0, false);

}

This is the end of your script... You're missing brackets { }
