Does anyone know why it says all the time "attempt to index a nil value"?

Hello, so i'm trying to load value from ReplicatedStorage into a normal leaderboard, but it just keep saying "ServerScriptService.LinkedLeaderboard:138: attempt to index a nil value".

Problem is in these lines:(Original lines)

local PlayerStats = game.ReplicatedStorage.PlayerStorage.Store:FindFirstChild(newPlayer.Name).PointsStorage
		if PlayerStats ~= nil then
			if cash then
				local Short = Settings.LeaderboardSettings.ShowShortCurrency
				PlayerStats.Changed:connect(function()
					if (Short) then
						cash.Value = Settings:ConvertShort(PlayerStats.Value)
					else
						cash.Value = Settings:ConvertComma(PlayerStats.Value)
					end
				end)
			end
		end

Even i tried to separate PointsStorage from it and add new line with it.

Here is changed a bit script:

local PlayerStats = game.ReplicatedStorage.PlayerStorage.Store:FindFirstChild(newPlayer.Name)
		if PlayerStats ~= nil then
local plrStats = PlayerStats:FindFirstChild("PointsStorage")
if plrStats ~= nil then
			if cash then
				local Short = Settings.LeaderboardSettings.ShowShortCurrency
				plrStats.Changed:connect(function()
					if (Short) then
						cash.Value = Settings:ConvertShort(plrStats.Value)
					else
						cash.Value = Settings:ConvertComma(plrStats.Value)
					end
				end)
				end
			end
		end

Error dissapeared, but script still don't work..

I'm noticing that cash either wasnt made or isnt visible. Please, if any if statements dont work, you must test and fix those immediately. I recommend using print statements
