help attempt to index a nil value (global 'Script')" } When running my script

[Kef0 0]

When running my script, Aurora returns this error (I got it through the debug.log.last):

"LUA", "message": "LUAERROR> Game:\\User\\Scripts\\Utility\\TestScript\\main.lua:14: attempt to index a nil value (global 'Script')" }

this is the only part that has a "Script." :

function DoShowMenu(menu)

    local ret = {}
    local canceled = false
    local menuItem = {}
    
    if menu == nil then
        ret, menu, canceled, menuItem = Menu.ShowMainMenu()
    else
        ret, menu, canceled, menuItem = Menu.ShowMenu(menu)
    end
    
    if not canceled then
        if Menu.IsMainMenu(menu) and menu.SubMenu == nil then
            Script.SetStatus("Teste1")
        end
        
        if menuItem.SubMenu ~= nil then
            DoShowMenu(menuItem.SubMenu)
        elseif not Menu.IsMainMenu(menu) then
            HandleSelection(ret, menu.Parent.Data, menu)
        else
            Script.ShowMessageBox("ERROR", "Test", "OK")
        end
    end
end

I'm new to this stuff, but I can't see what's wrong here. Any help here is useful, I'm clueless.
