My script I made is not really working at all! Can you see what's wrong?

here is my code :

local debounce = true

script.Parent.Touched:Connect(function(hit)
	if debounce == true then	
		if hit.Parent:FindFirstChild("Humanoid") then
			
			local char = hit.Parent
			local player = 	game.Players:GetPlayerFromCharacter(char)
--//------------------------------------------------------------------------------------------------------------------------------------------\\--
			print("Sold!")
			debounce = false
			player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + player.Knowledge.Value
			player.Knowledge.Value = 0
			wait(1)
			debounce = true
		end
	end
end)
