Can anyone help fix and simplify this datastore script?

return module

It doesn't save. Please helpp

It seems like you're attempting to save each 'Level Time' stat to a separate DataStore key. This works, but isn't as efficient as it could be. Here are some fixes you could make:

• You should save a table of all your data, and then you'll only need one key for your DataStore - as opposed to a separate key for every stat.

• Another way to increase efficiency in your code would be to use a numerical for loop while setting/getting your stats. This way, you don't have to type out so much.

#####Note: It looks like you may be using a ModuleScript. You should use a regular Script in ServerScriptStorage.

local Storage = game:GetService('DataStoreService'):GetDataStore("StatHolder")

game.Players.PlayerAdded:connect(function(plr)
	local data = Storage:GetAsync(plr.UserId);
	local Lvl = Instance.new("NumberValue", plr)
	Lvl.Name = "Lvl"
	Lvl.Value = data and data.Level or 1
	local LvlTime = Instance.new("IntValue", plr)
	LvlTime.Name = "LvlTime"
	for i = 1,12 do --numerical for for efficiency
		local this = "Lvl"..i.."Time";
		local lvlTime = Instance.new("StringValue",LvlTime);
		lvlTime.Name = this
		lvlTime.Value = data and data[this] or 0;
	end
end)


game.Players.PlayerRemoving:connect(function(plr)
	local data = {}; --make a table for the stats
	data.Level = plr:FindFirstChild("Lvl").Value --save level
	for i = 1,12 do --numerical for for efficiency
		--save individual values to table
		local this = "Lvl"..i.."Time";
		data[this] = plr.LvlTime:FindFirstChild(this).Value;
	end
	Storage:SetAsync(plr.UserId,data); --save table to datastore
end)
