Running Commands via NPC

[SynisterAU]

Hi,

So I'm attempting to run commands from addons via a NPC. My current .lua's are pretty much cut and paste from others and I've just done trial and error trying to get this console command to run. Here are my three files:

shared.lua
ENT.Type   = "ai"
ENT.Base   = "base_ai"
ENT.PrintName   = "gLevel NPC"
ENT.Author   = "N/A"
ENT.Purpose       = "To open gLevel"
ENT.Spawnable   = true
ENT.AdminSpawnable   = false

init.lua
AddCSLuaFile("cl_init.lua")
AddCSLuaFile("shared.lua")
include("shared.lua")

function ENT:Initialize()
self:SetModel("models/player/kleiner.mdl")
self:SetHullType( HULL_HUMAN )
self:SetHullSizeNormal( )
self:SetNPCState( NPC_STATE_SCRIPT )
self:SetSolid(  SOLID_BBOX )
self:CapabilitiesAdd( CAP_ANIMATEDFACE, CAP_TURN_HEAD )
self:SetUseType( SIMPLE_USE )
self:DropToFloor()

self:SetMaxYawSpeed( 90 )
end

function ENT:OnTakeDamage()
return false
end 

function ENT:AcceptInput(name, activator, caller)
if name == "Use" and caller:IsPlayer() then
RunConsoleCommand("gLevel.openMenu")
end

end

cl_init.lua
include("shared.lua")

function ENT:Draw()
self:DrawModel()
end

Again, a lot is cut and paste. In the above I'm attempting to open the gLevel menu from the addon, gLevel. It says its an "unknown command" so I assume RunConsoleCommand might only work with traditional commands and none from addons? If this is so, how do I go about achieving: A user pressing E (use) on a NPC and it opens up the menu from gLevel.

I have seen this accomplished on other servers (even with gLevel) and assumed it was via NPC, but if its another addon I need that does this please do let me know.

Thanks!
