[SOLVED] DataStoreService not loading data. May someone help me?

My Data Store will not save load a single thing. I do not know what I did wrong. There's nothing in the output. Here is my script:

local dataStoreService = game:GetService("DataStoreService")
local dataStore1 = dataStoreService:GetDataStore("Coins")
local dataStore2 = dataStoreService:GetDataStore("Level")
local dataStore4 = dataStoreService:GetDataStore("EXP")
game.Players.PlayerAdded:Connect(function(player)
	
	local data = Instance.new("Folder",player)
	data.Name = "Data"
	
	local level = Instance.new("IntValue",data)
	level.Name = "Level"
	level.Value = 1
	
	local coins = Instance.new("IntValue",data)
	coins.Name = "Coins"
	coins.Value = 0
	
	local exp = Instance.new("IntValue", level)
	exp.Name = "Exp"
	exp.Value = 0
	
	local maxExp = Instance.new("IntValue", level)
	maxExp.Name = "Max"
	
	local afk = Instance.new("BoolValue",player)
	afk.Name = "afk"
	afk.Value = false
	
	
	while wait(1) do
		maxExp.Value = 1000 + player["Data"].Level.Value
		if exp.Value >= maxExp.Value then
			level.Value = level.Value + 1
			exp.Value = 0
		end
	end

	local playerUserId = "player: "..player.UserId
	
	local data
	local data2
	local data3
	
	local success,errorMessage = pcall(function()
		data = dataStore1:GetAsync(playerUserId)
		data2 = dataStore2:GetAsync(playerUserId)
		data3 = dataStore4:GetAsync(playerUserId)
	end)
	if success then
		coins.Value = data
		level.Value = data2
		exp.Value = data3
		print("Loaded in "..player.Name.." and their stuff.")
	else
		warn(errorMessage)
	end
end)
game.Players.PlayerRemoving:Connect(function(player)
	local playerUserId = "player: "..player.UserId
	local data = player.Data.Coins.Value
	local data2 = player.Data.Level.Value
	local data3 = player.Data.Level.Exp.Value
	local success,errorMessage = pcall(function()
		dataStore1:SetAsync(playerUserId, data)
		dataStore2:SetAsync(playerUserId, data2)
		dataStore4:SetAsync(playerUserId, data3)
	end)
	if success then
		print("Saved data")
	else
		warn(errorMessage)
	end
end)
