Alright so this is a data script its a global script in ServerScriptService 

local DataStore = game:GetService("DataStoreService"):GetDataStore("HahaisdeadSave32")
local replicatedStorage = game:GetService("ReplicatedStorage")
local saveRemote = replicatedStorage:WaitForChild("Save")
local BloodAuto = replicatedStorage:WaitForChild("BloodAutoSave")


--creating data

saveRemote.OnServerEvent:Connect(function(player, val)
	DataStore:SetAsync(player.UserId, val)

end)

anything at all wrong with this?

saveRemote.OnServerEvent:Connect(function(player, val)
	DataStore:SetAsync(player.UserId, val)
	print("Successfully saved "..player.Name.."'s data!")
end)
