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

So why not make them Visible then Invisible at a timed interval?
You can do that, I'm just saying that you have the property wrong. You said it was in a GUI, so the correct property is ImageTransparency.
Changed it all to ImageTransparency, changing from = 1 to = 0 at each interval, no noticed change...
