How to change brick color?

PLEASE NOTE The title is supposed to be "Why is my script not working at all?"

I have this cash script that is in a part and the part is in workspace, The script basically is supposed to add 100 to the value on the "Cash" leaderstat. I am having trouble figuring out whats wrong with it and why it is not working...I have tried testing it on Studio and I also tested it on a roblox world but it is not working.. the output is empty and I can't seem to find the problem:

debounce = true

function Touch(part)
	if debounce then
		debounce = false
		local h = part.Parent:FindFirstChild("Humaniod")
		if h ~= nil then
			local player = game.Players.GetPlayerFromCharacter(part.Parent)
			if player then
				player:WaitForChild("leaderstats")
				player.leaderstats:WaitForChild("Cash")
				player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + 100
			end
		end
		debounce = true
	end
end

script.Parent.Touched:connect(Touch)

If somebody can help me that would be awesome... :D thanks

This should work. :)

debounce = true

function onTouch(Part)
	for _, player in ipairs(game.Players:GetPlayers()) do
		if player:FindFirstChildren("leaderstats") then
			player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + 100
			debounce = false
		end
	end
end

script.Parent.Touched:connect(onTouch)
