14:08:21.857 - ServerScriptService.CurrencyScript1.1:34: attempt to index field 'LocalPlayer' (a nil value)

local DataStore  = game:getService( "DataStoreService")
local Storage = DataStore:GetDataStore( "SaveSystem")

game.Players.PlayerAdded:Connect(function(plr)
	local folder =Instance.new("Folder")
	folder.Name = "leaderstats"
	folder.Parent = plr
	
	local Kills = Instance.new("IntValue")
	Kills.Name = "Kills"
	Kills.Value = 0
	Kills.Parent = folder
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"

	cash.Parent = folder
	 
	local success, result = pcall(function()
		Storage:GetAsync(plr.UserId)
	end)
	
	if not success  then
		warn(result)
	else

		if LoadTable then
			Kills.Value = LoadTable[1]
			cash.Value = LoadTable[2]
		end
	end
end)

-- game.Players.LocalPlayer.PlayersRemoving:Connect(function(plr)
	local SaveTable = {plr.leaderstats.Kills.Value.plr.leaderstats.Cash.Value}
	Storage:SetAsync(plr.UserId. SaveTble)
end)

#Players Service & PlayerRemoving.

The PlayerAdded and PlayerRemoving Signals are both apart of the Players` Service. These Signals can only be accessed with the pertaining Service.

Instead, you accidentally called game.Players.LocalPlayer.PlayerRemoving, which wouldn't work as the LocalPlayer is a PlayerObject, not the actual Service required to Listen for these Signals.

You also cannot call the LocalPlayer from the Server as it's not an actual Client, therefore it doesn't have it's own PlayerObject, or anything related.

You will also get another error with line 35. This is because you continued to traverse through the leaderstats folder looking for something that won't be found by the Script.

Ascending through an Object is done by the ., you forgot to separate the two desired Elements to upload through the SaveTable array, which can be done by using a ,. Without this, it will look for plr in Kills' value, which is a big nono.

Revised Code

game.Players.PlayerRemoving:Connect(function(plr)
	local SaveTable = {plr.leaderstats.Kills.Value,plr.leaderstats.Cash.Value}
	Storage:SetAsync(plr.UserId, SaveTable) --// You said 'SaveTble', Comma here too for giving it the second argument, and in general.
end)

you wrote

game.Players.LocalPlayer.PlayersRemoving:Connect(function(plr)
  local SaveTable = {plr.leaderstats.Kills.Value.plr.leaderstats.Cash.Value}
    Storage:SetAsync(plr.UserId. SaveTble)
end)

this is the fix

game.Players.PlayerRemoving:Connect(function(plr)
  local SaveTable = {plr.leaderstats.Kills.Value,plr.leaderstats.Cash.Value}
    Storage:SetAsync(plr.UserId. SaveTble)
end)

the reason your code didn't work is because PlayerRemoving isn't part of the player, it's a member of the Players service where all the players are, as well as that the "LocalPlayer" can't be fetched by a server script.

anyways hope this helped!
