How to make a player body scaling changes visible to other players?

So i have been trying to make a game where you have to change body part sizes to complete an obstacle course. Here is the local script:

I know I have to use remote events and stuff but everything I have tried doesn't work.

local player = game.Players.LocalPlayer
local IQ = Instance.new("NumberValue")
IQ.Value = 100
IQ.Name = "IQ"
IQ.Parent = game.Workspace
IQ.Parent = game.Players.LocalPlayer.Character




local function OnClick()
	
	local person = player.Character
	person.Humanoid.HeadScale.Value = person.Humanoid.HeadScale.Value + 0.1000000000000000000
	IQ.Value = IQ.Value + 10
	if person.Humanoid.HeadScale.Value > 4 then
		person.Humanoid.HeadScale.Value = 4
	end
	
	if IQ.Value > 400 then
		IQ.Value = 400
	end
end


script.Parent.MouseButton1Click:Connect(OnClick)

This happens when your remote event set fire on client so people in the server couldn’t see it, you must set the Remote Event Fire on Server, this will be the example : Example :

local remote = game.ReplicatedStorage.RemoteEvent

remote.OnServerEvent:Connect(function()
   print(“Fired!”)
end

That script will able everyone in the server see the print! This is the fire script server to the printing script working example :

game.ReplicatedStorage.RemoteEvent:FireServer()

Try this code, if everyone on the server see it, try to execute it with your script, if not work, reply me this comment! Because I’m not in the studio but it must work for you!
