local debris = game:GetService("Debris")
	local marketplace = game:GetService("MarketplaceService")	
	
	while true do	
		local shout = marketplace:GetProductInfo(173676511).Description
		if string.sub(shout, 1, 1) == "1" then
			local hint = Instance.new("Hint", workspace)
			hint.Text = string.sub(shout, 3, string.len(shout))
			debris:AddItem(hint, 10)
		end
		wait(10)
	end

The point of the script is that when I put testing123, 1, 1 in the Models Desc it would make a hint instead of that game saying testing123. But I don't know if I am doing it right, can you guys please explain how to do it right? Thank you!
