I'm really new to LUA... I try to make a Summon module for Summoner, and took some other code and try to wrap my head around ;)

I have this, but as soon as I try to change the ID setting in the GUI, the game crashes... what am I missing?

Code:
-- Create a new table for our code:

Summon= { }

-- Some local variables we use in our module:

Summon.running = false

Summon.lastticks = 0

function Summon.ModuleInit()

    if (Settings.Summon.SumEnabled == nil) then

        Settings.Summon.SumEnabled = "0"

    end

    GUI_NewWindow("Summon",50,50,100,50)

    GUI_NewCheckbox("Summon","Enabled","SumEnabled", "Main")

    GUI_NewNumeric("Summon","ID:","idvalue","Options")

    GUI_SizeWindow("Summon",150,120)

    SumEnabled = Settings.Summon.SumEnabled

    idvalue = Settings.Summon.idvalue

end

function Summon.GUIVarUpdate(Event, NewVals, OldVals)

    for k,v in pairs(NewVals) do

        if (     k == "SumEnabled" or

                k == "idvalue")

        then

            Settings.Summon[tostring(k)] = v

        end

    end

    GUI_RefreshWindow("Summon")

end

function Summon.OnUpdateHandler( Event, ticks )

    if ( SumEnabled == "1" and ticks - Summon.lastticks > 500 ) then

        Summon.lastticks = ticks

        if ( Player:IsMoving() == false) then

            local mypet = Player.pet

            --if ( TableSize(mypet) == 0) then

                --local action = ActionList:Get(idvalue)

                --if ( action ) then

                --    d("ID: ".. tostring(action.id))

                --end

            --end

        end

    end

end

RegisterEventHandler("Module.Initalize",Summon.ModuleInit)

RegisterEventHandler("GUI.Update",Summon.GUIVarUpdate)

RegisterEventHandler("Gameloop.Update",Summon.OnUpdateHandler)

and: is there a way to test code outside the game? It really takes time to change a bit, then start the game over and over again ;)

Edit: got it, seems the Settings file was corrupt...
