I'm new to Lua scripting and DataStorage. I have the PlayerStatsManager Script as Shown (Stored in game.ServerStorage) (I have also seen similar questions to mine with little/no responses)

-- Setup table that we will return to scripts that require the ModuleScript.
local PlayerStatManager = {}
 
-- Create variable for the DataStore.
local DataStoreService = game:GetService('DataStoreService')
local playerData = DataStoreService:GetDataStore('PlayerData')
 
-- Create variable to configure how often the game autosaves the player data.
local AUTOSAVE_INTERVAL = 60
 
-- Number of times we can retry accessing a DataStore before we give up and create
-- an error.
local DATASTORE_RETRIES = 3
 
-- Table to hold all of the player information for the current session.
local sessionData = {}
 
-- Function the other scripts in our game can call to change a player's stats. This
-- function is stored in the returned table so external scripts can use it.
function PlayerStatManager:ChangeStat(player, statName, childStat, changeValue)
	sessionData[player][statName][childStat] = sessionData[player][statName][childStat] + changeValue
end

function PlayerStatManager:SetStat(player, statName, childStat, newValue)
	sessionData[player][statName][childStat] = newValue
end

function PlayerStatManager:GetData(player,statName,childStat)
	return (sessionData[player][statName][childStat])
end
 
-- Function to retry the passed in function several times. If the passed in function
-- is unable to be run then this function returns false and creates an error.
local function dataStoreRetry(dataStoreFunction)
	local tries = 0	
	local success = true
	local data = nil
	repeat
		tries = tries + 1
		success = pcall(function() data = dataStoreFunction() end)
		if not success then wait(1) end
	until tries == DATASTORE_RETRIES or success
	if not success then
		error('Could not access DataStore! Warn players that their data might not get saved!')
	end
	return success, data
end
 
-- Function to retrieve player's data from the DataStore.
local function getPlayerData(player)
	return dataStoreRetry(function()
		return playerData:GetAsync(player.UserId)
	end)
end
 
-- Function to save player's data to the DataStore.
local function savePlayerData(player)
	if sessionData[player] then
		return dataStoreRetry(function()
			return playerData:SetAsync(player.UserId, sessionData[player])
		end)
	end
end
 
-- Function to add player to the sessionData table. First check if the player has
-- data in the DataStore. If so, we'll use that. If not, we'll add the player to
-- the DataStore.
local function setupPlayerData(player)
	local success, data = getPlayerData(player)
	if not success then
		-- Could not access DataStore, set session data for player to false.
		sessionData[player] = false
	else
		if not data then
			print"what lol"
			-- DataStores are working, but no data for this player
			sessionData[player] = {}
			sessionData[player] = {Coins = 10, Escapes = 0, Vip = false}
			savePlayerData(player)
		else
			-- DataStores are working and we got data for this player
			sessionData[player] = data
		end
	end	
end
 
-- Function to run in the background to periodically save player's data.
local function autosave()
	while wait(AUTOSAVE_INTERVAL) do
		for player, data in pairs(sessionData) do
			savePlayerData(player)
		end
	end
end
 
-- Bind setupPlayerData to PlayerAdded to call it when player joins.
game.Players.PlayerAdded:connect(setupPlayerData)
 
-- Call savePlayerData on PlayerRemoving to save player data when they leave.
-- Also delete the player from the sessionData, as the player isn't in-game anymore.
game.Players.PlayerRemoving:connect(function(player)
	savePlayerData(player)
	sessionData[player] = nil
end)
 
-- Start running autosave function in the background.
spawn(autosave)
 
-- Return the PlayerStatManager table to external scripts can access it.
return PlayerStatManager

And I'm trying to call that script inside of my leaderboard script, located in game>Workspace>Main>Stats. This is what I have so far, and I'm attempting to reach it by calling Wins.Value = PlayerStatManager:GetData(Player, "Wins", 0)

PlayerStatManager = require(game.ServerStorage.PlayerStatManager)

game.Players.PlayerAdded:connect(function(Player)

	-- Folders
	local Folder = Instance.new("Folder", Player)
	Folder.Name = 'leaderstats'
	
	local settingFolder = Instance.new("Folder", Player)
	settingFolder.Name = 'PlayerSettings'
	
	-- Player
	local Playing = Instance.new('BoolValue', Player)
	Playing.Name = 'Playing'
	Playing.Value = false
	local isAFK = Instance.new('BoolValue', Player)
	isAFK.Name = 'isAFK'
	isAFK.Value = false
	
	-- Leaderboard
	local Escapes = Instance.new('IntValue', Folder)
	Wins.Name = 'Wins'
	Wins.Value = PlayerStatManager:GetData(Player, "Wins", 0)
	print(Wins.Value)
	
	local Coins = Instance.new('IntValue', Folder)
	Coins.Name = 'Coins'
	Coins.Value = PlayerStatManager:GetData(Player, "Coins", 10)
	print(Coins.Value)
	
	-- In-game Leaderboard
	local Kills = Instance.new("IntValue", settingFolder)
	Kills.Name = "Kills"
	Kills.Value = 0
	
end)

I'm new to DataStorage, and keep getting nil value errors. The most recent error reads 18:55:55.154 - ServerStorage.PlayerStatManager:29: attempt to index field '?' (a nil value) I've toggled with this script a little and get different errors, but they all result in this sort of error.

I'm just trying to save and store data right now. Can't get passed this error
