AddAccessory does not work in-game, am I not waiting for something?

Sorry for one question so quickly after the other. In my last question, I was asking how to use AddAccessory properly. Now I've gotten my answer and it works perfectly in Studio, no bugs! However, when I launch a test server and then test it out, I click on the button that the hat comes from and absolutely nothing happens. This has happened before, and it was because I was not Finding First Child or I didn't wait for everything to be identified. Can someone help me quickly identify the thing I need to fix here so it will work in-game? The code is shown below:

function click()
	local accessory = game.Lighting.meshes.example:Clone()
	local player = game.Players.LocalPlayer
	local playercharacter = game.Players.LocalPlayer.Character
	local playername = player.Name
	local humanoid = game.Workspace:FindFirstChild(playername)
	
	--Hat Equips Here
	accessory.Parent = playercharacter
end

script.Parent.MouseButton1Click:connect(click)

You were referencing the player's character twice, and naming the second reference "humanoid". Also, I don't see where you have used AddAccessory member function.

Here is the edited version

function click()
	local accessory = game.Lighting.meshes.example:Clone()
	local player = game.Players.LocalPlayer
	local playercharacter = player .Character or player.CharacterAdded:wait()
	local humanoid = playercharacter:WaitForChild("Humanoid", 2)

	--//After we have tried getting the humanoid, check if it is there
	if humanoid then
		--Hat Equips Here
		humanoid:AddAccessory(accessory)
	else
		print("No humanoid found")
	end
end

script.Parent.MouseButton1Click:connect(click)

I would recommend you also take a look at these:

Humanoid Class: http://wiki.roblox.com/index.php?title=API:Class/Humanoid

The AddAccessory member function of the humanoid: http://wiki.roblox.com/index.php?title=API:Class/Humanoid/AddAccessory

The Accessory, this is passed in the AddAccessory member function: http://wiki.roblox.com/index.php?title=API:Class/Accessory

it doesn't work because AddAccessory() only works on the server, try to find another way to put the hat on
