cron a nil value?

[lua\autorun esting.lua:5] attempt to index global ‘cron’ (a nil value)

So I do all that work of getting the cron and shit to work… and now it won’t get cron. SWEET!

[lua]
VIPList = {}

require ‘cron’

cron.RegisterJob( “unvip”, function( sid )
v:SetUserGroup( “user” )
PrintMessage( HUD_PRINTTALK, v:Name()…"'s VIP has expired and revoked." )
end )

local function addVIP( ply, text )
local sep = string.Explode( " “, text )
if sep[1] == (”!ad" or “!add” or “!addv” or “!addvi”) then
draw.SimpleText( “!addvip <name> <# of months>”, “Trebuchet20”, 130, ScrH()*0.827, Color(0,0,0,255), TEXT_ALIGN_LEFT, TEXT_ALIGN_CENTER)
end
if sep[1] == “!addvip” and ply:IsUserGroup( “owner” ) then
local months = tonumber( sep[3] )
if not months then return ply:PrintMessage( HUD_PRINTTALK, “Invalid amount of months.” ) end

    local name = table.concat( sep, " ", 2 )
    for k,v in pairs( player.GetAll() ) do
        if v:Name():lower():find( name:lower() ) then
            v:SetUserGroup( "VIP" )

            local t = os.date( "*t" )
            local conf = {
                Minutes = t.min,
                Hours = t.hour,
                Days = t.day,
                Months = (t.month%12 + months)
            }

            cron.Add( "vip_" .. v:SteamID(), conf, "unvip", v:SteamID() )
			local newvip = {}
			newvip[ "name" ] = v:GetName()
			newvip[ "steamID" ] = v:SteamID()
			newvip[ "months" ] = months
			newvip[ "timeLeft" ] = ""
			table.insert( VIPList, newvip )

            PrintMessage( HUD_PRINTTALK, ply:Name() .. " made player ".. v:Name() .. " a VIP for "..months.." months." )
            break
        end
    end

elseif sep[1] == "!vipmenu" and ply:IsUserGroup( "owner" ) then
	RunConsoleCommand( "vip_menu" )

elseif sep[1] == "!removevip" and ply:IsUserGroup( "owner" ) then
	local name = table.concat( sep, " ", 2 )
	for k,v in pairs( player.GetAll() ) do
        if v:Name():lower():find( name:lower() ) then
			v:SetUserGroup( "user" )
			PrintMessage( HUD_PRINTTALK, v:Name().."'s VIP has been revoked forcefully." )
		end
	end
end

end
hook.Add ( “PlayerSay”, “addVIP”, addVIP )

function VIPMenu()
local VIPMenu = vgui.Create( “DFrame” )
VIPMenu:SetPos( (ScrW()/2) - VIPMenu:GetWide(),(ScrH()/2) - VIPMenu:GetTall() )
VIPMenu:SetSize( 500, 700 )
VIPMenu:SetTitle( “V.I.P. Menu” )
VIPMenu:SetVisible( true )
VIPMenu:SetDraggable( true )
VIPMenu:ShowCloseButton( true )
VIPMenu:MakePopup()

local VIPListView = vgui.Create( "DListView", VIPMenu )
VIPListView:SetPos(25, 50)
VIPListView:SetSize(450, 625)

for k,v in pairs( VIPList ) do
	VIPListView:AddLine( v.name, v.steamID, v.months, "Working on it. :(" )
end

local button = vgui.Create("DButton", VIPMenu)
button:SetTitle("Remove")
button:SetPos() -- Your pos
button:SetSize( 50, 20 ) -- Your size
button.DoClick = function(btn)
local id = VIPListView:GetSelectedLine() -- Getting the line id
	for k,v in pairs( player.GetAll() ) do
		if v:SteamID() == VIPList[id].steamID then
			v:SetUserGroup( "user" )
		end
	PrintMessage( HUD_PRINTTALK, VIPList[id].name.."'s VIP has been revoked forcefully." )
	cron.Remove( "vip_"..VIPList[id].steamID )
	VIPListView:RemoveLine( id )
	end
end

concommand.Add( “vip_menu”, VIPMenu )
[/lua]

At line 3, you have,
[lua]require ‘cron’[/lua]

which should be,
[lua]require( ‘cron’ )[/lua]

That’s not an issue. If there is only one argument to a function, and it is a string, you don’t need to wrap it in parenthesis.

There isn’t a default cron module in the game, so that is probably the issue there.

Assuming a custom module, make sure you have it installed correctly.

Well great… The person that told me to use cron never told me that i had to install a custom module…

I have no idea how to install and where to get it.

EDIT:

Dun Derp’ed; I didn’t download the cron module that he had posted on my thread I asked about it in.

Downloading and testing now.
