Blur Does not Disable?

Ok so it enables it but when it comes to disabling it, it doesnt, it keeps it checked.

hint = script.Parent

while true do
game.Lighting.LoadBlur.Enabled = "True"
hint.Text = "Loading"
wait(.5)
hint.Text = "Loading."
wait(.5)
hint.Text = "Loading.."
wait(.5)
hint.Text = "Loading..."
wait(.5)
hint.Text = "Loading"
wait(.5)
hint.Text = "Loading."
wait(.5)
hint.Text = "Loading.."
wait(.5)
hint.Text = "Loading..."
wait(.5)
hint.Text = "Loading"

wait(2)
game.Lighting.LoadBlur.Enabled = "False"
hint.Parent.Parent:Destroy()
