I saw a post, where this script successfully worked for this guy, but its not working for me...

if SERVER then
    AddCSLuaFile()
    return
end
 
local function ChatToWebsite(ply, txt)
    if (ply == LocalPlayer() and string.sub(txt, 1, 6) == "!rules") then
        MsgN("Hook worked.")
        gui.OpenURL("http://google.com")
        return true
    end
end
hook.Add("OnPlayerChat", "ChatToWebsite", ChatToWebsite)

I'm new to lua scripts with gmod, and the way i added it to my server was making a folder in the "Addons" folder.
In that folder, i made another one called "lua" and a addon.txt file with the necessary information.
In the lua folder, i made another folder called autorun, and finally in that folder a lua file called "shared.lua".

In the shared.lua file i pasted the code i previously stated before.

I think i did the process correct, is it the script that dosen't work? Or is it the way i setup the Addon?

Please help! If so correct the code!

Thanks for reading!
