Lua Expected <eof>

[HeyAwesomePeopl]

I run this code:

while true do
repeat
redstone.Output("right", true)
sleep(10)
redstone.Output("right", false)
sleep(2)
until false
end
end

And this error comes up:
bios:206: [string "startup"]:9: '<eof>' expected

Help please. Very new to this.

while true do
repeat
redstone.Output("right", true)
sleep(10)
redstone.Output("right", false)
sleep(2)
until false
end

Try this. I assume this is only a part of script, because it's not even a full lua file.
