Error with the LocalPlayer, Can you help me?

I don't understand why but he sends me an error message " 16:48:55.855 - Workspace.Tycoon.Starter.Collector.Touch.Script:6: attempt to index nil with 'leaderstats' 16:48:55.855 - Stack Begin 16:48:55.856 - Script 'Workspace.Tycoon.Starter.Collector.Touch.Script', Line 6 16:48:55.856 - Stack End" and I think he can't find the localizer because when I put my roblox name it works here are my scripts for my leaderboard:

function onPlayerEntered(newPlayer)
	local leaderstats = Instance.new("IntValue")
	leaderstats.Name = ("leaderstats")
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Value = 1000
	cash.Parent = leaderstats
	
	leaderstats.Parent = newPlayer
end

game.Players.ChildAdded:connect(onPlayerEntered)

for my script:

player = game.Players.LocalPlayer

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") 
	then
		player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + script.Parent.Parent.screen.Amount.Value		
		script.Parent.Parent.screen.Amount.Value = 0
	end
end)

A few errors here, but don't worry, I think I can fix them!

1: You must make sure that 'leaderstats' is a folder , not an IntValue. Roblox is very specific about that.

2: You define the leaderstats' parent after defining the cash. Instead, define its parent before cash because it is the parent of cash. Look to the code below to solve these first two steps:

function onPlayerEntered(newPlayer)
	local leaderstats = Instance.new("Folder", newPlayer) --this sets this as a folder and makes the parent of the leaderstats the player who just joined
	leaderstats.Name = "leaderstats"

Anymore issues please comment, if this solved your issue please accept it as an answer :)
