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

[ingedoom]

Could this be it? Seems like you misplaced your parenthesis.

if(GetLeverState("Lever1") == -1
&& GetLeverState("Lever2" ) == 1)
&& GetLeverState("Lever3" ) == -1
&& GetLeverState("Lever4" ) == -1

edit: also the puzzle function does not seem to have a closing bracket.
edit:

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

{
UnlockDoor(string &in asEntity, int LeverState);
}

else
{ SetSwingDoorLocked("Door", false, true);
PlaySoundAtEntity("", "door_safety_open.ogg", "Door", 0, false);
}
}

I think that should do it.
