		[email protected]$ = [email protected]$ + "SELECT `amount` FROM `inventory` WHERE `nameid` = "+.item_id;
		[email protected]$ = [email protected]$ + " UNION ";

		for ([email protected] = 0; [email protected] < [email protected]; [email protected]++)
			[email protected]_amount += [email protected][[email protected]];
		
		setiteminfo .item_id, ITEMINFO_SELL, (.max_amount / [email protected]_amount);
