Why isn't my Data Store system working?

local dataStore = game:GetService("DataStoreService"):GetDataStore("myStore")

function userEntered(newPlayer)
	local clientFolder = Instance.new("Folder")
	clientFolder.Parent = newPlayer
	clientFolder.Name = "Client Data"
	
	local knockouts = Instance.new("IntValue")
	knockouts.Parent = clientFolder
	knockouts.Name = "Knockouts"
	knockouts.Value = 0
	
	local gamesPlayed = Instance.new("IntValue")
	gamesPlayed.Parent = clientFolder
	gamesPlayed.Name = "Games Played"
	
	local userKey = "usr-"..newPlayer.UserId
	local dataTable = dataStore:GetAsync(userKey)
	
	if dataTable then
		knockouts.Value = dataTable[1]
		gamesPlayed.Value = dataTable[2]
	else
		print(1)
		local dataTable = {knockouts.Value, gamesPlayed.Value}
		dataStore:SetAsync(userKey, dataTable)
	end
end


function userLeaving(oldPlayer)
	local userKey = "usr-"..oldPlayer.UserId
	local clientFolder = oldPlayer:FindFirstChild("Client Data")
	local dataTable = {clientFolder.Knockouts.Value, clientFolder["Games Played"].Value}
	
	dataStore:SetAsync(userKey, dataTable)
end

game.Players.PlayerAdded:Connect(userEntered)
game.Players.PlayerRemoving:Connect(userLeaving)

When I run the game, the values show as "0" as if the Data Store did not load the values. Does anyone know why?

Thank you.
