My text engine localscript isn't working?

A script in StarterGui > ScreenGui > Frame > Textlabel > LocalScript

Code:

local TextLabel = script.Parent

while true do
    wait(1)
    TextLabel.Text = "Loading"
    wait(1)
    TextLabel.Text = "Loading."
    wait(1)
    TextLabel.Text = "Loading.."
    wait(1)
    TextLabel.Text = "Loading..."
end

And it's just not letting it load!
