BigNum DataStore Error

I have a problem with the Bignum module i dont really know how to make datastore with it i tried it but i failed :confused:

The Bignum module is very long thats because i uploaded on pastebin :slight_smile: --[[ Big Number Library made by ido - Pastebin.com
The Module is in ReplicatedStorage

Here is the Datastore i tried:

local x = require(game.ReplicatedStorage.BigNum)
local data = game:GetService("DataStoreService"):GetDataStore("CoinCoin")

game.Players.PlayerAdded:Connect(function(plr)
	script.Stats:Clone().Parent = plr
	local ls = plr.Stats
	local money = ls.Money
	local multiplier = ls.Multiplier
	local load = data:GetAsync(tostring(plr.UserId))
	if load then
		money.Value = load[1]
		multiplier.Value = load[2]
	end
	
	while wait(0.05) do
		local svb = x.convert(money.Value)
		local val = x.convert(0.5)
		local val = x.mul(val,(x.mul(x.convert(multiplier.Value),{1,0})))
		svb = x.add(svb,val)
		money.Value = x.bnumtostr(svb)
		
		
		local lvl = x.convert(0)
		if x.me(x.convert(money.Value), x.convert(1)) then
            lvl = x.add(x.mul(x.log10(x.convert(money.Value))))
		end
		if x.me(x.convert(multiplier.Value), x.convert(1)) then
            lvl = x.add(x.mul(x.log10(x.convert(multiplier.Value))))
		end
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	data:SetAsync(tostring(plr.UserId),{
        plr.Stats.Money.Value,
        plr.Stats.Multiplier.Value,
	})
end)
