I don't know lua or the modules themselves that well...

function items.check_turn_in(trade, trade_check)
	--create trade_return table == trade
	--shallow copy
	local trade_return = {};
	for key, value in pairs(trade) do
		trade_return[key] = value;
	end
	
	--for every item in trade_check check trade_return
		--if item exists in trade_return then 
			--remove that item from trade_return
		--else
			--failure
	for i = 1, 4 do
		local key = "item" .. i;
		if(trade_check[key] ~= nil and trade_check[key] ~= 0) then
			local found = false;
			for j = 1, 4 do
				local inst = trade_return["item" .. j];			
				if(inst.valid and trade_check[key] == inst:GetID()) then
***				->	trade_return["item" .. j] = ItemInst();
					found = true;
					break;
				end
			end
			
			if(not found) then
				return false;
			end
		end
	end
...
end

There is a 'default' constructor declared for ItemInst in lua: https://github.com/EQEmu/Server/blob...minst.cpp#L269

..but, there doesn't appear to be a definition: https://github.com/EQEmu/Server/blob...eminst.cpp#L11


That said, the marked line should probably be:

trade_return["item" .. j] = ItemInst(inst:GetID());

..or..

trade_return["item" .. j] = inst;

I honestly just don't know since I don't code these scripts...
