Clone script only cloning once instead of repeating?

I am attempting to make something that clones a brick repeatedly on a timer. But it isn't working. Someone else's post on the DevForum said to move the script into a different brick and have it work from there but that isn't working either. I also tried turning it into a function and I am just very confused. Also I can't use Instance.New because the place that I am spawning from is a moving object. Here is my script:

local MarbleL = script.Parent.Parent.Parent.MarbleLeft:Clone()
local Marble1 = script.Parent.Parent.Parent.MarbleLeft




function CreateMarble()
    wait(1)
    Marble1:Clone()
    MarbleL.Parent = game.Workspace.TireMarbles
    MarbleL.Transparency = 0
    MarbleL.CanCollide = true
    MarbleL:ClearAllChildren()
    print("Working")
end
while 1 < 5 do
CreateMarble()
end

I hope I formatted this right, thanks in advance for your help :) Edit: I only started scripting like 2 days ago so if my scripting is sloppy or bad that's probably why
