you are initializing the ranplayerv as a string (or array). remove the [MAX_PLAYERS] from it, so it becomes a "simple" integer again, which is used in your line...
i use a similar code:

Код:

	TogglePlayerSpectating(playerid,1);
	new Veh;
	Veh=GetPlayerVehicleID(observed);
	if (Veh==0)
	{
		PlayerSpectatePlayer(playerid,observed);
	}
	else
	{
	  PlayerSpectateVehicle(playerid,Veh,SPECTATE_MODE_NORMAL);
	}
