Leaderstat value is nil ?

Soooo. This problem is a time dissolver. I'm trying to do a game (rpg) with abilities and skills BUT , there is the thing : There's a level system and i wish the abilities to evolve with the level... There's the script... :(

local repstore = game:WaitForChild("ReplicatedStorage")
local Remote = repstore.OFA:WaitForChild("Punch")

Remote.OnServerEvent:connect(function(player) 
	LDS = player:FindFirstChild("leaderstats")
	Level = LDS.Level
end)

function onTouched(hit)
	local human = hit.Parent:FindFirstChild("Humanoid")
	if (human ~= nil ) and debounce == false and human ~= script.Parent.Parent.Humanoid then
		human:TakeDamage(Level.Value * 3)
		local position = Instance.new("BodyVelocity",hit.Parent.HumanoidRootPart)
		position.MaxForce = Vector3.new(999999999999999,9999999999999,999999999999999)
		position.P = 300
		position.Velocity = script.Parent.Parent:FindFirstChild("LowerTorso").CFrame.UpVector * 5
		game.Debris:AddItem(position,0.1)
		script.Disabled = true
		debounce = true
		wait(1)
		debounce = false
	end
end

script.Parent.Touched:connect(onTouched)

local repstore = game:WaitForChild("ReplicatedStorage")
local Remote = repstore.OFA:WaitForChild("Punch")

Remote.OnServerEvent:connect(function(player) 
	LDS = player:FindFirstChild("leaderstats")
	Level = LDS.Level
end)

(This part was used to get local player)

The attack deals damage but when i increase the level, attack damage don't increase. My life is a entire nightmare because of this.

Any help is accepted. Thanks for reading. Arthas.

EDIT : This script goes with an other one :

local repstore = game:WaitForChild("ReplicatedStorage")
local Remote = repstore.OFA:WaitForChild("Punch")



Remote.OnServerEvent:connect(function(player) 
	LArm = player.Character:WaitForChild("LeftLowerArm") 
		RArm = player.Character:WaitForChild("RightLowerArm")
local human = player.Character:FindFirstChild("Humanoid")
local canattack = true 
		local Damage2 = script.Damage:Clone()
		Damage2.Parent = RArm
		canattack = false
		human:LoadAnimation(script.L):Play()
		Damage2.Disabled = false
		wait(0.6)
		Damage2:Destroy()
		canattack = true
		end)

EDIT2 : I think i do everything wrong because of my unexpericence with lua.

In the onTouched function you never call call the RemoteEvent therefor the script doesn't know what level you are

There is no need to do ["Level"], you can simply do Level. Object names in brackets usually have more than one word in their name, which is why they have brackets. Lua can't detect an object name with more than one word without brackets.

As for a nil debunk-er:

local level = LDS:FindFirstChild("Level")
if level then
	-- Code
end

This should fix your problem, as it checks to see if the value actually exists or not. If it doesn't, the script stops.
