I don't know how to convert my script to LocalScript correctly without breaking it?

I've tried every tutorial I've found on every possible platform, but to no avail. Can anyone show me the proper way to convert this to a working LocalScript without it breaking? The script is completely functional on Studio but not the game itself.

repeat wait() until game.Players.LocalPlayer.Character
wait(1)
game:GetService("Players")
local player = game.Players.LocalPlayer
local egghunt = player.Character.Humanoid
print("Cash")

function onPlayerEntered(newPlayer)
	wait(.25)
	local stats = Instance.new("IntValue")
	stats.Name = "leaderstats"
	local stats2 = Instance.new("IntValue")
	stats2.Name = "Cash"

	local cash = Instance.new("IntValue")
	
	cash.Name = "Cash"
	cash.Value = 0

	cash.Parent = stats
	stats2.Parent = newPlayer	
	stats.Parent = newPlayer
end

game.Players.ChildAdded:connect(onPlayerEntered)
