Attempted to call global Room (a nil value)

[gononono64]

Hey there,
I'm trying to set up a table in a way that i can pass it as an object. Essentially i want to be able to use obj:function() features.
I'm currently trying to create a room that hold tiles (table serverside) and players steamids for checks. However when i try to create a room upon GM:PlayerInitialSpawn() I get a nil value. And i dont know why.
include( 'sRoom.lua' )

concommand.Add("create_room", function(ply, cmd, args )

    local room = Room(ply:SteamID()) -- this is where i get the error
    room:setName("Hello world")
    print( room:getOwner() .." has joined " .. room:getName() )

end)

This is my room metatable

local Room = {}
Room.__index = Room

function Room:new(owner, name, public, players, tiles, items, banned)

    local EmptyRoom = {

        owner = owner or "",
        name = name or "",
        public = public or false,
        players = players or {},
        tiles = tiles or {},
        items = items or {},
        banned = banned or {}

    }

    return setmetatable(EmptyRoom, Room)
end
Ive just been going off of this: Object Oriented Lua
So if anyone has any idea what im doing wrong, I would love to hear from ya.
Thanks again

You're calling the function like
Room()
when you have defined it to be
Room:new()
