Motor6D "Left Shoulder" and "Right Shoulder" not reconnecting arms?(SOLVED)

I just made it clone the motor and reweld everything

I'm new to scripting so don't judge me So this is an animation (using cframe) when you press R problem is though, arm falls off after animation and doesn't go back to normal. Help please?

Player = game.Players.LocalPlayer
mouse = Player:GetMouse()

mouse.KeyDown:connect(function (key)
if script.value.Value == true then
if key == "r" then
script.Parent.attack.value.Value = false
script.value.Value = false
if Player.Character:FindFirstChild("Blades1") ~= nil and Player.Character:FindFirstChild("Blades2") ~= nil then
local b1 = Player.Character:FindFirstChild("Blades1")
local re1 = script.bladre:Clone()
re1.Parent = b1
Player.Character:FindFirstChild("Left Arm").Blades1:remove()
b1.Middle.Velocity = b1.Middle.CFrame.lookVector * 25
b1.Parent = game.Workspace
b1.blade.CanCollide = true
re1.Disabled = false
script.reload:Play()
local b2 = Player.Character:FindFirstChild("Blades2")
local re2 = script.bladre:Clone()
re2.Parent = b2
Player.Character:FindFirstChild("Right Arm").Blades1:remove()
b2.Middle.Velocity = b2.Middle.CFrame.lookVector * 25
b2.Parent = game.Workspace
b2.blade.CanCollide = true
re2.Disabled = false
end

if Player.Character:FindFirstChild("Blades1") == nil and Player.Character:FindFirstChild("Blades2") == nil then
 local torso = Player.Character:FindFirstChild("Torso")
    local arm1 = Player.Character:FindFirstChild("Left Arm")
    local arm2 = Player.Character:FindFirstChild("Right Arm")
    local weld1 = Instance.new("Weld" , Player.Character:FindFirstChild("Left Arm"))

    weld1.Part0 = torso
    weld1.Part1 = arm1
    local ls = Player.Character:FindFirstChild("Torso"):FindFirstChild("Left Shoulder")
    local rs = Player.Character:FindFirstChild("Torso"):FindFirstChild("Right Shoulder")
