My ManualWeld Does not Appear to be Working for any Reason At all??

local inputservice = game:GetService("UserInputService")

local tweenservice = game:GetService("TweenService")

inputservice.InputBegan:Connect(function(input,controller)

if controller then return end

if input.KeyCode == Enum.KeyCode.P then

print"P has been pressed."

-- the part is cylinder and the CFrame don't work because it does not face the way I look!!!

local energywave = game.ReplicatedStorage.Part:Clone()

energywave.CFrame = script.Parent.LeftLowerArm.CFrame

energywave.Parent = game.Workspace

-- welding here

local weld = energywave.Weld

weld.Part0 = energywave

weld.Part1 = script.Parent.LeftLowerArm

-- tweening

local goal = {}

goal.Size = Vector3.new(100,3,3)

local tweeninfo = TweenInfo.new(2)

local tween = tweenservice:Create(energywave,tweeninfo,goal)

tween:Play()

end

end)

Ignore this, just placing your script in a code block

local inputservice = game:GetService("UserInputService")

local tweenservice = game:GetService("TweenService")

inputservice.InputBegan:Connect(function(input,controller)

if controller then return end

if input.KeyCode == Enum.KeyCode.P then

print"P has been pressed."

-- the part is cylinder and the CFrame don't work because it does not face the way I look!!!

local energywave = game.ReplicatedStorage.Part:Clone()

energywave.CFrame = script.Parent.LeftLowerArm.CFrame

energywave.Parent = game.Workspace

-- welding here

local weld = energywave.Weld

weld.Part0 = energywave

weld.Part1 = script.Parent.LeftLowerArm

-- tweening

local goal = {}

goal.Size = Vector3.new(100,3,3)

local tweeninfo = TweenInfo.new(2)

local tween = tweenservice:Create(energywave,tweeninfo,goal)

tween:Play()

end

end)
