Why wont my attack boosting script in my sword work?

Sorry for posting again. Making An rpg is hard. I made a sword that works, but when i added attack boosting by levels it doesnt. there are no errors, can someone help? Non-Attack Boost:

local tool = script.Parent
local debounce = true

tool.Handle.Touched:Connect(function(hit)
	local humanoid = hit.Parent.Humanoid
	if humanoid and humanoid.Parent ~= tool.Parent then
			if debounce == true then
				debounce = false
				humanoid:TakeDamage(20)
		end
	end
end)

tool.Activated:Connect(function()
	local toolanim = Instance.new("StringValue")
	toolanim.Name = "toolanim"
	toolanim.Value = "Slash"
	toolanim.Parent = tool
	debounce = true
end)

with attack boost:

local tool = script.Parent
local player = game.Players:GetPlayerFromCharacter(tool.Parent)
local debounce = true

tool.Handle.Touched:Connect(function(hit)
	local humanoid = hit.Parent.Humanoid
	if humanoid and humanoid.Parent ~= tool.Parent then
		if player then
			if debounce == true then
				debounce = false
				humanoid:TakeDamage(20 * (player.leaderstats.Level.Value +1))
			end
		end
	end
end)

tool.Activated:Connect(function()
	local toolanim = Instance.new("StringValue")
	toolanim.Name = "toolanim"
	toolanim.Value = "Slash"
	toolanim.Parent = tool
	debounce = true
end)
