Cant access Data Store?

(This code is in a normal script not a local script) I'm just trying to simply have make a Data Store script to save money called "Dino Dollars". But when I run my game no errors occur but money doesnt save and when I manually run the script I keep getting the "DataStore can't be accessed from client" error. If anyone could see an error I dont that would be very helpful thx.

local DSS = game:GetService('DataStoreService'):GetDataStore('test1212123')

game.Players.PlayerAdded:Connect(function(plr)
	local unique = 'id-'..plr.userId
	local leaderstats = Instance.new('IntValue',plr)
	local savevalue = Instance.new('IntValue')
	leaderstats.Name = 'leaderstats'
	savevalue.Parent = leaderstats
	savevalue.Name = 'Dino Dollars'
	
	
	local GetSaved = DSS:GetAsync(unique)
	if GetSaved then
		savevalue.Value = GetSaved[1]
		print("First")
	else
		local NumbersForSaving = {savevalue.Value}
		DSS:SetAsync(unique, NumbersForSaving)
		print("ElseLine")
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local unique = 'id-'..plr.userId
	local Savetable = {plr.leaderstats.DinoDollars.Value}
	DSS:SetAsync(unique, Savetable)
	print("Final")
end)

The error does not say what line it just says "DataStore can't be accessed from client".
