Why doesnt anything pop up on the screen, am i doing something wrong ?

Here is my code. it is inside a local script and i cant figure out whats going on. Output has no errors so what do i do

player = game.Players.LocalPlayer

player.CharacterAdded:connect(function()
    local intro = Instance.new("ScreenGui")
    local introframe = Instance.new("Frame")
    local introimage = Instance.new("ImageLabel")
    intro.Parent = game.StarterGui
    introframe.Parent = intro
    introimage.Parent = introframe
    introframe.Visible = true
    introimage.Visible = true

end)
