Need a little help scripting

[Virtualdarks]

Well, I'm fresh here from ROBLOX. I been a 3 year veteran there, and still playing it. The Lua conversion is getting me a little. Here's the script I wrote:

while true do

newboxo = create("Box")
newboxo.Name = "newboxo"
newboxo.Size = Vector3.new(3,3)
newboxo.Parent = game.World
newboxo.Position = script.Parent.Position
newboxo.Fixed = false
sleep(2)
newboxo:remove()

end

What's suppose to happen is that a new "Box" appears at the position of the currently existing Box, then drop, then 2 seconds later, removes itself.

If something in the script is obsolete in Buildism, please tell me.

Yes I do know RBX.Lua. It's just much simpler in ROBLOX.
