DataStore not loading/saving leaderstats??

Here's the code to load the stats:

local DataStore = game:GetService("DataStoreService"):GetDataStore("SurvivalsStorage")

game.Players.PlayerAdded:connect(function(player)

local stats = Instance.new("IntValue", player)
stats.Name = "leaderstats"
local Survivals = Instance.new("IntValue" , stats)
Survivals.Name = "Survivals"

local Key = "user-"..player.userId

local SaveWins = DataStore:GetAsync(Key)

if SaveWins then
	--save format: 
	Survivals.Value = SaveWins[1]
else
	local ValuesToSave = {Survivals.Value}
	DataStore:SetAsync(Key, ValuesToSave)
end

end)

game.Workspace.ChildAdded:connect(Findthenoob)

Here's the code that saves the stats:

local DataStore = game:GetService("DataStoreService"):GetDataStore("SurvivalsStorage")

game.Players.PlayerRemoving:connect(function(player)

	local Key = "user-"..player.userId
	
	local ValuesToSave = {player.leaderstats.Survivals.Value}
	DataStore:SetAsync(Key, ValuesToSave)

end)

Both are Server scripts in workspace
