Question about an error!

[Worshipper]

[highlight]If you have no intelligent comments, keep them for yourself.[/highlight]

I'll try to explain you what's my problem because my english is really bad.
I coded a simple inventory system for my roleplay gamemode and when I'm testing it online, people are getting an error when they try to open the derma menu (F1). I don't get their error and it works fine for me.

This is the [highlight]error[/highlight] they got:
[lua]madcows_roleplay\gamemode\cl_menu.lua:158: attempt to index field 'bigbeerbottle' (a nil value)[/lua]

I send the items to the client so they're supposed to see the big beer bottle (inventory.lua):
[lua]
// Send to client all items.
local files = file.FindInLua("madcows_roleplay/gamemode/items/*.lua")
for k, v in pairs(files) do
AddCSLuaFile("items/" .. v)
end
[/lua]

Items and function tables (shared.lua):
[lua]
MAD = {}

// Main table
Inventory = {}

// Items table
Inventory.Items = {}
[/lua]

This is the cl_menu.lua:

Perhaps I'm not seeing the entire code, but I don't see anywhere where you actually put things into the Inventory.Items table. If you are, then my guess is the FindInLua or AddCSLuaFile paths may not be correct. Try doing a PrintTable(Inventory.Items) and see what comes out.

[Worshipper]

I don't understand because the AddCSLuaFile is supposed to be perfect.

What file are all the items defined in? Shared? If it's shared, did you make sure to send it to the client as well as cl_menu?

[Worshipper]

I forgot to include all the items in shared.lua.
I found the solution at 3 AM. :P
[lua]
// Include all items both serverside and clientside.
local files = file.FindInLua("madcows_roleplay/gamemode/items/*.lua")
for k, v in pairs(files) do
include("items/" .. v)
end
