So my blocks just fall off the map,can someone help?

local enabled = true
Player = script.Parent.Parent
mouse = Player:GetMouse()
run = game:GetService("RunService")
local Left_Arm = script.Parent:FindFirstChild("Left Arm")
local Right_Arm = script.Parent:FindFirstChild("Right Arm")
local Core = script.Parent:FindFirstChild("Torso")
local Left_Leg = script.Parent:FindFirstChild("Left Leg")
local Right_Leg = script.Parent:FindFirstChild("Right Leg")
function onKeyDown(key)
	key = key:lower()
	if key == "t" then
		game:GetService("Chat"):Chat(Player.Character.Head, "Focus the mind, reflect upon yourself, and determine the goal.")
		Left_Arm = Instance.new ("Part")
		Right_Arm = Instance.new("Part")
		Core = Instance.new("Part")
		Left_Leg = Instance.new("Part")
		Right_Leg = Instance.new("Part")
		Left_Arm.BrickColor = BrickColor.new("White")
		Left_Arm.Size = Vector3.new(2, 3, 2)
		Left_Arm.TopSurface = "Smooth"
		Left_Arm.BottomSurface = "Smooth"
		Left_Arm.Transparency = 0.7
		Left_Arm.CanCollide = false
		Left_Arm.CFrame = Player.Character["Left Arm"].CFrame *CFrame.new(2, 3, 2)
		Left_Arm.Parent = workspace
		Right_Arm.BrickColor = BrickColor.new("White")
		Right_Arm.Size = Vector3.new(2, 3, 2)
		Right_Arm.TopSurface = "Smooth"
		Right_Arm.BottomSurface = "Smooth"
		Right_Arm.Transparency = 0.7
		Right_Arm.CanCollide = false
		Right_Arm.CFrame = Player.Character["Right Arm"].CFrame *CFrame.new(2, 3, 2)
		Right_Arm.Parent = workspace
		Core.BrickColor = BrickColor.new("White")
		Core.Size = Vector3.new(3, 3, 2)
		Core.TopSurface = "Smooth"
		Core.BottomSurface = "Smooth"
		Core.Transparency = 0.7
		Core.CanCollide = false
		Core.CFrame = Player.Character["Torso"].CFrame *CFrame.new(3, 3, 2)
		Core.Parent = workspace
		Left_Leg.BrickColor = BrickColor.new ("White")
		Left_Leg.Size = Vector3.new(2, 3, 2)
		Left_Leg.TopSurface = "Smooth"
		Left_Leg.BottomSurface = "Smooth"
		Left_Leg.Transparency = 0.7

		Right_Leg.Size = Vector3.new(2, 3, 2)
		Right_Leg.TopSurface = "Smooth"

		Right_Leg.Transparency = 0.7
		Right_Leg.CanCollide = false
		Right_Leg.CFrame = Player.Character["RightLeg"].CFrame *CFrame(2, 3, 2)
		Right_Leg.Parent = workspace
		local weld = Instance.new("Weld")
		weld.part0 = Left_Arm
		weld.C0 = Left_Arm.CFrame:inverse()
		weld.part1 = script.Parent:FindFirstChild("Left Arm")		
	end
end

mouse.KeyDown:connect(onKeyDown)

and i get this error 21:59:16.900 - Players.kingalpha1.Backpack.LocalScript:49: attempt to call global 'CFrame' (a table value)
