Script is not working

This is from a tutorial, but it doesn’t work.

I want to make my character click a button to get bigger.

There are no errors in the output.

local button = script.Parent.Parent
local ClickDetector = script.Parent


ClickDetector.MouseClick:Connect(function(player)
	local char = player.Character
	local Human = char.Humanoid
	 
	local depth = Human:WaitForChild("BodyDepthScale")
	local height = Human:WaitForChild("BodyHeightScale")
	local width = Human:WaitForChild("BodyWidthScale")
	local head = Human:WaitForChild("HeadScale")
	
	local properties = {depth, height, width, head}
	
	for i,property in pairs(properties) do
		wait(1)
		local changeBy = math.random(-1, 1)
		property.Value = property.Value + changeBy
		
	end
end)

I tried this and it works.
Seems to be the changeBy variable causing the problem

local Button = script.Parent.Parent
local ClickDetector = script.Parent

ClickDetector.MouseClick:Connect(function(Player)
	local Char = Player.Character
	local Human = Char.Humanoid

	local Depth = Human:WaitForChild("BodyDepthScale")
	local Height = Human:WaitForChild("BodyHeightScale")
	local Width = Human:WaitForChild("BodyWidthScale")
	local Head = Human:WaitForChild("HeadScale")

	local Properties = {Depth, Height, Width, Head}

	for _, Property in pairs(Properties) do
		Property.Value = math.random(50, 150) / 100
	end
end)

No, still doesnt work.

Oof the chars

I’d rather use :FindFirstChild instead of :WaitForChild since the child you are searching for is already inside humanoid when a player is going to click on the click detector and you don’t have to wait for it to be added there. You might not face an error but because of that, you might receive a warning called infinite yield possible.

Maybe, this might help.

local button = script.Parent.Parent
local ClickDetector = script.Parent


ClickDetector.MouseClick:Connect(function(player)
	local char = player.Character
    if char then
	     local Human = char:FindFirstChild("Humanoid")
	     if Human then
	           local depth = Human:FindFirstChild("BodyDepthScale")
               local height = Human:FindFirstChild("BodyHeightScale")
	           local width = Human:FindFirstChild("BodyWidthScale")
	           local head = Human:FindFirstChild("HeadScale")
	
	           local properties = {depth, height, width, head}
	
               for i,property in pairs(properties) do
                   if property then
		                property.Value += 1
                   end
 	          end
        end
   end
end)
