My Gun Script Is not letting me pass multiple arguments?

local script

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Mouse = game.Players.LocalPlayer:GetMouse()
local player = game.Players.LocalPlayer


script.Parent.Equipped:Connect(function()
	Mouse.Icon = "rbxasset://textures/GunCursor.png"
end)

script.Parent.Unequipped:Connect(function()
	Mouse.Icon = "rbxasset://SystemCursors/Arrow"
end)


script.Parent.Activated:Connect(function()
	if Mouse.Target.Name == ("Target") then
		game.Workspace.GunShot:Play()
		Mouse.Target:Destroy()
		local GunLevel = script.Parent.GunLevel
		ReplicatedStorage.GunHit:FireServer(player, GunLevel)
	end	
	
	
end)

global script

local ReplicatedStorage = game:GetService("ReplicatedStorage")





game.Players.PlayerAdded:Connect(function(player)

	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	local Points = Instance.new("IntValue")
	Points.Name = "GunHits"
	local GunLevel = Instance.new("IntValue")
	GunLevel.Name = "GunLevel"
	GunLevel.Value = 1
	leaderstats.Parent = player
	Points.Parent  = leaderstats
	GunLevel.Parent = leaderstats
	
	

	

end)

ReplicatedStorage.GunHit.OnServerEvent:Connect(function(player, GunLevel)
	player.leaderstats.GunHits.Value = player.leaderstats.GunHits.Value + GunLevel.Value
end)
