How to add more walk sounds then one?

So I have this walk sound script that plays sound when you go on material and it only plays one audio when you step on like a random material I want to add more sounds to this wood material since it only plays 1 audio when you step on the wood

Put it in a "while true do" loop and loop through the sound and try this

while true do
	wait(1) --adjust the speed u want to replay the sound so u can match it with the animation
	*play sound here*
end
