Gun local script, or gun server script not working?

Greetings, I tried to make a gun, a Glock17, and made those scripts which makes you able to shoot, reload, double damage touching the enemy's head, with guis, animations, compatible in mobile, and compatible with Filtering Enabled on, but it doesn't work for some reason. Could I get some help, please?

1st Script, inside the tool:

local Tool = script.Parent --Getting the Tool
local Player = game:GetService("Players").LocalPlayer -- Getting the Player
local Mouse1 = Player:GetMouse() -- Getting Player's Mouse
local GunFire = Tool:WaitForChild("GunFire") -- Getting the Shoot sound
local Reload = Tool:WaitForChild("Reload") -- Getting the Reload sound
local Torso = "" -- Getting the Player's Torso
local Reloading = false -- Prevents spamming the reload event
local ContextActionService = game:GetService("ContextActionService") -- Allows us to cater for Mobile Players
local BodyType = nil -- Getting the player's bodytype (R6 or R15), nil for now
local Difference = 0 -- Geting distance between the bullet and the gun
local ReplicatedStorage = game:GetService("ReplicatedStorage") -- Getting ReplicatedStorage
local GunGui = Tool:WaitForChild("GunGui") -- Getting the Gui
local Bullets = Tool:WaitForChild("Bullets") -- Getting the Bullets
local ReloadTime = 3 -- Setting the Reload Time

-- [[REMOTE EVENTS]]

local EquipAnimation = ReplicatedStorage:WaitForChild("EquipAnimation") -- Getting Remote event
local Headshot = ReplicatedStorage:WaitForChild("Headshot") -- Getting Remote event
local Reload = ReplicatedStorage:WaitForChild("Reload") -- Getting Remote event
local ShootEvent = ReplicatedStorage:WaitForChild("ShootEvent") -- Getting Remote event
local UnequipAnimation = ReplicatedStorage:WaitForChild("UnequipAnimation") -- Getting Remote event

-- [[REMOTE FUNCTIONS]]

local CheckBodyType = ReplicatedStorage:WaitForChild("CheckBodyType") -- Getting Remote Function
local FetchBulletsLeft = ReplicatedStorage:WaitForChild("FetchBulletsLeft") -- Getting Remote Function

-- [[FIND BODY TYPE]]

function FindBodyType() -- Getting the player's bodytype (R6 or R15)
	BodyType = CheckBodyType:InvokeServer(Tool) -- Invoking Remote Function checking if player's bodytype is R6 or R15
	print(BodyType) -- Print the bodytype of the player
end

-- [[RELOADING FUNCTION]]

function ReloadFunction()

end

-- [[TOOL EQUIPING]]

	Mouse1.Icon = "http://www.roblox.com/asset?id=936803887" --Changing mouse Icon
	mouse.Button1Down:Connect(function()
		if Bullets.Value <= 0 or Reloading == true then
			-- Don't do anything

			GunFire:Play()
			if Difference.Magnitude < 1.33 then
				ShootEvent:FireServer(Tool,Position,Part)
				Bullets.Value = Bullets.Value - 1
			end
		end
	end)
	local ReloadMobileButton = ContextActionService:BindAction("ReloadButton",ReloadFunction(),true,"r")
	ContextActionService:SetPosition("ReloadButton",UDim2.new(0.72,-25,0.2,-25))
	ContextActionService:SetImage("ReloadButton","http://www.roblox.com/asset?id=10952420")
