Would this GetChildren script work?

game.Players.PlayerAdded:connect(function(Player)

    function Leaderstats()
        Leaderstats = Instance.new("IntValue")
        Leaderstats.Parent = Player
        Leaderstats.Name = "Leaderstats"

        LeaderstatsChildren = Leaderstats:GetChildren()

        for LeaderstatsCount = 1, #LeaderstatsChildren do
            Leaderstats.Value = Leaderstats.Children
        end
    end

    function PowerLevel()

    end

    function Attack()

    end

    function Defense()

    end

    function Agility()

    end

    function Rank()

    end

    Leaderstats()
    PowerLevel()
    Attack()
    Defense()
    Agility()
    Rank()  

end)
