Im new, and I need help on this localscript that produces particles, more info in desc..?

So I am creating a localscript that produces particles out of the right arm of a player, and it won't work. The particles will either just stay in one spot if anchored, and if not anchored it will just fall off. Also this is not cancollide. Read the script.

local UserInputService = game:GetService("UserInputService")
Player = game.Players.LocalPlayer
mouse = Player:GetMouse()

repeat wait() until Player.Character

local char = Player.Character
local torso = char:findFirstChild("Torso")
local rightarm = char:findFirstChild("Right Arm")

enabled = true

HoldVariable = 0

local function onInputBegan(input,gameProcessed)
	if input.KeyCode == Enum.KeyCode.E and HoldVariable == 0 then
		HoldVariable = 1
		torso.Anchored = true
		local keyPressed = input.KeyCode
		local hum = game.Players.LocalPlayer.Character.Humanoid
		local anim_feet = hum:LoadAnimation(script.Parent.RArmAnim)
		local current = anim_feet
		current:Play()
		wait(0.7)
		local part = char["Right Arm"]:Clone()
		part.BrickColor = BrickColor.new('Institutional white')
		part.Material = "Neon"
		part.Name = "RightArm2"
		part.CFrame = rightarm.CFrame
		part.Anchored = true
		part.CanCollide = false
		wait()
		part.Parent = char
		for i = 1, 10 do
			part.Size = part.Size +Vector3.new(0.1,0.1,0.1)
			part.Transparency = part.Transparency + 0.1
			part.CFrame = rightarm.CFrame
			wait()
		end
		part:destroy()
		rightarm.BrickColor = BrickColor.new('Gold')
		rightarm.Material = 'Neon'
		rightarm.Reflectance = 0
		local x = game.ReplicatedStorage.Flame:Clone()
		x.Parent = workspace
		x.CFrame = rightarm.CFrame*CFrame.new(0, 0, 0)
		torso.Anchored = false
	
	end
end

UserInputService.InputBegan:connect(onInputBegan)

PLS HELP ASAP!
