Why won't it set the text?

Hierarchy of the script:

• ScreenGui

  • Frame

    • LocalScript

    • TextLabel

For some reason, the following script won't work. No errors in the output or anything.

game.Players.PlayerAdded:connect(function(plr)
    print(plr.Name)
    wait()
    script.Parent.TextLabel.Text = plr.Name
end)
