How do I freeze the character in place?

This script to freeze the character isn't working. Help?

local player = game.Players.LocalPlayer
local torso = player:WaitForChild('UpperTorso')

torso.Anchored = true

UpperTorso is within the Character, not the Player.

I've created a variable character. The or statement is there in case the script loads before the character does, which would result in an error.

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local torso = character:WaitForChild("UpperTorso")
wait(2)
torso.Anchored = true

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local head = character:FindFirstChild("Head") or character:WaitForChild("Head")
head.Anchored = true

or

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:FindFirstChild("Humanoid") or character:WaitForChild("Humanoid")
local canjump = false

humanoid.WalkSpeed = 0

humanoid:GetPropertyChangedSignal("Jump"):Connect(function()
	if canjump == false then
	humanoid.Jump = false
	end
end)

or

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:FindFirstChild("Humanoid") or character:WaitForChild("Humanoid")

if humanoid.RigType == Enum.HumanoidRigType.R15 then
local uppertorso = character:FindFirstChild("UpperTorso") or character:WaitForChild("UpperTorso")
uppertorso.Anchored = true
elseif humanoid.RigType == Enum.HumanoidRigType.R6 then
local torso = character:FindFirstChild("Torso") or character:WaitForChild("Torso")
torso.Anchored = true
end
