Script WON'T transition through GUI. Why? [One Answer, No help]

I am making a 'movie' gui thing for my place, but the GUI doesn't transition through the Decals. Also yeah, I know I have used probably the least efficient way of doing the script anyways. Annoying because this same script with a bit of tweaking WILL work on Decals placed on Parts...

movie = script.Parent

while true do
wait(5)
movie.q.Visible = true
movie.w.Visible = false
movie.e.Visible = false
movie.r.Visible = false
movie.t.Visible = false
movie.y.Visible = false
movie.u.Visible = false
movie.i.Visible = false

wait(5)
movie.q.Visible = false
movie.w.Visible = true

wait(5)
movie.w.Visible = false
movie.e.Visible = true

wait(2)
movie.e.Visible = false
movie.r.Visible = true

wait(3)
movie.r.Visible = false
movie.t.Visible = true

wait(2.5)
movie.t.Visible = false
movie.y.Visible = true

wait(2)
movie.y.Visible = false
movie.u.Visible = true

wait(1)
movie.u.Visible = false
movie.i.Visible = true
end
