Just wondering if there was a way in shortening this script, while still keeping the Value's of the Size.
function Countdown()
script.Parent.FontSize = "Size32"
wait()
script.Parent.FontSize = "Size28"
wait()
script.Parent.FontSize = "Size24"
wait()
script.Parent.FontSize = "Size18"
wait()
script.Parent.FontSize = "Size14"
wait()
script.Parent.FontSize = "Size12"
wait()
script.Parent.FontSize = "Size11"
wait()
script.Parent.FontSize = "Size12"
wait()
script.Parent.FontSize = "Size14"
wait()
script.Parent.FontSize = "Size18"
wait()
script.Parent.FontSize = "Size24"
wait()
script.Parent.FontSize = "Size28"
wait()
script.Parent.FontSize = "Size32"
end

You can cut the length of array in half by going forward then back. If you're being extra short you could pull the "Size" part into the loop and out of the array.
Even shorter, since FontSize is an Enum (http://wiki.roblox.com/index.php?title=API:Enum/FontSize), you can store its integer value instead (i.e. sizes = {11, 10, 7, 6, 5, 4, 3, 4, 5, 6, 7, 10, 11})
Hmm, I did not know that myself. I have yet to really delve into GUI's. Good to know though, thanks for sharing.
