Why is this function failing to get the Gui's position?

Every time I run this function and put the the Gui's position it creates the Points position at (0,0,0,0) why and how do I fix it?

Local Script(Updated):

local Player = game.Players.LocalPlayer
-----------------------------------------
function CreateGui()
local ScreenGui = Instance.new("ScreenGui",Player.PlayerGui)
    ScreenGui.Name = "Stuff"
local Frame = Instance.new("Frame",ScreenGui)
    Frame.Position = UDim2.new(0,350 ,0,200)
    Frame.Size = UDim2.new(0,100    ,0,100)
return Frame
end
-----------------------------------------
function CreatePoints(Position)
    print("Given Position for function CreatePoints() is: ",Position)
    -----------------
    function FindScreenGui()
    local Found = Player.PlayerGui:FindFirstChild("Stuff")
    if not Found then
        local ScreenGui = Instance.new("ScreenGui",Player.PlayerGui)
        return ScreenGui
    else 
        return Found
    end
    -----------------
    end
    local ScreenGui =  FindScreenGui()
    local Point = Instance.new("Frame",ScreenGui)
        Point.Position = Position
        Point.Size = UDim2.new(0,10 ,0,10)
--      Point.BackgroundColor = Color3.new(255/255,0/255,0/255)-- I'll fix part later
        return Point
end
-----------------------------------------
function GetCenterOfGui(Gui)

absoluteXS = Gui.AbsoluteSize.X
absoluteYS = Gui.AbsoluteSize.Y

absoluteXP = Gui.AbsolutePosition.X
absoluteYP = Gui.AbsolutePosition.Y
return UDim2.new(0, absoluteXP + (absoluteXS/2), 0, absoluteYP + (absoluteYS/2))
end
-----------------------------------------
local Gui = CreateGui()
--local Point = CreatePoints(UDim2.new(Gui.Position.X.Scale
--                          ,Gui.Position.X.Offset,
--                          Gui.Position.Y.Scale,
--                          Gui.Position.Y.Offset))
local Middle = GetCenterOfGui(Gui)
local Point = CreatePoints(Middle)
