Not Accessing the LocalPlayers Arms?

Hi, when this script is run in studio, it works fine. However, in game, I get this error: Right Arm is not a valid member of Model.

Extra Information: LocalScript inside Starterpack.

Do not pay attention to the commented lines of code.

local player = game.Players.LocalPlayer
local character = player.Character
if not character or not character.Parent then
	character = player.CharacterAdded:wait()
game.Players.LocalPlayer.Character["Right Arm"].Transparency = 1
game.Players.LocalPlayer.Character["Left Arm"].Transparency = 1
--game.Players.LocalPlayer.Character.Torso.Transparency = 1
local arm1 = script.Placearmsinhere.RightArm:Clone()

arm1.Parent = game.Workspace

local arm2 = script.Placearmsinhere.LeftArm:Clone()
arm2.Parent = game.Workspace

--local torso = script.Placearmsinhere.Torso:Clone()
--torso.Parent = game.Players.LocalPlayer.Character

wait(1)


local weld1 = Instance.new("Weld")
weld1.Parent = game.Players.LocalPlayer.Character.Torso
weld1.Part1 = game.Players.LocalPlayer.Character["Right Arm"]
weld1.Part0 = arm1
weld1.C0 = CFrame.Angles(0, 0 ,0 )

local weld2 = Instance.new("Weld")
weld2.Parent = game.Players.LocalPlayer.Character.Torso
weld2.Part1 = game.Players.LocalPlayer.Character["Left Arm"]
weld2.Part0 = arm2
weld2.C0 = CFrame.Angles(0, 0 ,0 )

--[[local weld2 = Instance.new("Weld")
weld2.Parent = game.Players.LocalPlayer.Character.Torso
weld2.Part1 = game.Players.LocalPlayer.Character.Torso
weld2.Part0 = torso
weld2.C0 = CFrame.Angles(0, 0 ,0 )
]]

end

Try adding below line 4 this script:

repeat wait() until character:FindFirstChild("Right Arm")  ~= nil and character:FindFirstChild("Left Arm") 

The Error can be caused by the Arms not being loaded yet, when you try to get them.
