why wont the part weld properly to the other part in my tool??

RepStorage = game:GetService("ReplicatedStorage")
Remote = RepStorage:WaitForChild("DashEvent")

Remote.OnServerEvent:Connect(function(Player)
	local BV = Instance.new("BodyVelocity", Player.Character.HumanoidRootPart)
	BV.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
	BV.Velocity = Player.Character.HumanoidRootPart.CFrame.LookVector*100 
	game.Debris:AddItem(BV, 1) 
	
	local Clone = game.Lighting.DashEffect:Clone()
	local hitpart = script.Parent.Parent.Handle:WaitForChild("HitPart")
	local W = Instance.new("Weld")
	W.Part0 = hitpart
	W.Part1 = Clone
	Clone.Parent = hitpart
	Clone.CFrame = hitpart.Cframe*CFrame.new(0,0,-1)
	i = Player.Character.Head.Orientation.Y
	Clone.Orientation = Vector3.new(0,i,0)
	
local Clone = game.Lighting.DashEffect:Clone()
	local W = Instance.new("Weld")
	W.Part0 = hitpart
	W.Part1 = Clone
	Clone.Parent = hitpart
	Clone.CFrame = hitpart.Cframe*CFrame.new(0,0,-1)
	i = Player.Character.Head.Orientation.Y
	Clone.Orientation = Vector3.new(0,i,0)	
	end)

so im trynna weld sumthing to a part in my tool but it doesnt work the part that i clone just spawns in workspace at 0,0,0 help is apreciated
