Trying to fix Roblox's "Dummy" model's WalkAndTalk script (Repost)

Hey! I already made a post on this but I am remaking it because there were some things I left out that I shouldn’t have. I don’t know if this is allowed on the DevFourm so please tell me!

Anyway, I have a script that makes the Dummy walk around and talk. But, I am getting an error that I don’t know how to fix.

Here is the script:

function getRandomPhrase()
	local playerName = script.Parent.Target.Value.Parent.Name
	local phrases = {
		playerName:upper() .. " IS IN THIS SERVER!!1",
		"I MET " .. playerName:upper(),
		"give " .. playerName:lower() .. " some space!",
		"how did you get famous?",
		"omg " .. playerName .. " plz don8",
		"OMG LEAVE " .. playerName:upper() .. "ALONE",
		playerName:upper() .. "!!1",
		playerName .. " is just a normal person guys",
		"will u don8",
		"i am your biggest fan",
		"how much robux u got?",
		"plz join my group",
		"HOLY TELAMON ITS " .. playerName:upper(),
		"my brother loves ur game",
		"im putting this in my blurb",
		"second famous person i met 2day",
		"GIVE " .. playerName:upper() .. " SPACE!!",
		playerName:upper(),
		playerName:lower(),
		"no wonder famous people never talk",
		"do you talk?",
		"will you donate 100k R$ to me?",
		"come to my place i need to show u a glitch",
		"how much will u donate?",
		"i can't believe it's " .. playerName,
		"can u make me famous?",
		"are you afk?",
		"why wont you talk to me?",
		"famous ppl never donate",
		"famous people are greedy",
		playerName .. " do you donate?",
		"whats it like being a famous person?",
		"how much tix u got man?",
		"make me famous and ill give u 23 tix",
		"can i copy ur game?",
		"there are hackers at your game, plz ban them",
		"buy gear from my place",
		"can i take a screenshot?",
		"i am recording this lol"
	}
 	return phrases[math.random(#phrases)]
end

local function plusOrMinus(number)
	return math.random(number - 4, number + 4)	
end

local function randomize(v)
	return Vector3.new(plusOrMinus(v.X), plusOrMinus(v.Y), plusOrMinus(v.Z))
end

wait(math.random())
local walkspeed = script.Parent.Humanoid.WalkSpeed
local hum = script.Parent.Humanoid
local head = script.Parent.Head
local torso = script.Parent.Torso
local target = script.Parent.Target.Value
while true do
	if (torso.Position - target.Position).magnitude < 2 then
		hum.WalkSpeed = 0
	else
		hum.WalkSpeed = walkspeed
		hum:MoveTo(randomize(target.Position), target)
	end
	game:GetService("Chat"):Chat(head, getRandomPhrase())
	wait(1)
end

The line it is failing on is:

if (torso.Position - target.Position).magnitude < 2 then

And here is the error:

Workspace.erik.cassel.WalkAndTalk:62: attempt to index nil with 'Position'

Help would be appreciated, thanks!

You arent providing an exception for target and since this is an infinite loop the thread has no time to update its state. Either provide a default value or check if it is nil

I’m not entirely sure what you mean as I am not that advanced in scripting.

The error says everything you need to know. attempt to index nil with 'Position' means you are trying to get nil.Position. This means that either torso or target are nil. Put a print(torso, target) before the while loop to know which one is missing.

If it’s the Torso that’s missing, and it’s because you updated the dummy’s rig, then just make it the HumanoidRootPart of the dummy.

Set the Target ObjectValue to a Part or a characters Torso
