--Purpose:Creates a movable model using rays and mouse events

--[[Setup]]--

Player = game.Players.LocalPlayer
-------------------------------
Vairables = {
	Part = game.ServerStorage.Part,
	Mouse = Player:GetMouse()}
-------------------------------
Functions = {
	CreateRay = function(IgnorePart)
	local Ray = Ray.new(Vairables.Mouse.UnitRay.Origin,Vairables.Mouse.UnitRay.Direction*900)--Create ray from mouse and reaches 900 studs max
	local Hit,Pos = game.Workspace:FindPartOnRay(Ray,IgnorePart)--Ray,PartIgnoredByRay
	return Hit 
end}
-------------------------------
ClonedPart = Vairables.Part:Clone()
ClonedPart.Parent = game.Workspace

 --~~--~~[[Everything starts here]]~~--~~---
	Vairables.Mouse.TargetFilter = Player.Character
	 Vairables.Mouse.Move:connect(function()
		 local Hit = Functions.CreateRay(ClonedPart)
		 if  Hit then -- if hit then do the following
		 ClonedPart:MoveTo(Vairables.Mouse.Hit.p)
		 end
	 end)
 -----------------------------------------
	 Vairables.Mouse.Button1Down:connect(function()
	   	 local NewPart = ClonedPart:Clone()
	     NewPart.Parent = game.Workspace
	 end)

Why won't it work and how do I fix it?
