How do I correctly store StringValue with DataStore2?

So this is me getting the StringValue and then putting it into a dictionary so I can do deserialization and then serialize it again into a value/increment so the datastore can store it. What I'm trying to do right now is get the datastore with DataStore2:Get() I've tried a few ways and it hasn't worked does anyone have any ideas?

game.Players.PlayerAdded:Connect(function(player)
local data = Instance.new("Folder", player); data.Name = "Database"

local names = Instance.new("StringValue", data); names.Name = "NameValue"

local NAME_VALUE = player.Database.NameValue.Value

local ItemsDictionary = {
	["namevalue"] = player.Database.NameValue.Value
}
	
local nameStore = DataStore2("Name", player)

nameStore:BeforeInitialGet(function(serialized)
	
	local deserialized = {}

	for _, id in pairs(serialized) do
		local playerName = ItemsDictionary[id]
		deserialized[playerName] = true
		print(deserialized)
	end

	return deserialized
end)

nameStore:BeforeSave(function(deserialized)

	local serialized = {}

	for playerName in pairs(deserialized) do
		for NameId, name in pairs(ItemsDictionary) do
			if name == playerName then
				table.insert(serialized, NameId)
				print(serialized)
			end
		end
	end

	return serialized
end)
