Datastore not recognizing when a value updates?

My datastore does not recognize when a player's leaderstat value (e.g. Money) changes. I cannot see the issue with it however and cannot figure out what is wrong (and I know that doing amount.Changed isn't the smartest thing but I can fix that later). Can anyone more experienced take a look? Here's the datastore script:

local DataStore = game:GetService("DataStoreService")
local DS1 = DataStore:GetDataStore("StatsDataStore")

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

    local leader = Instance.new("Folder", player)
    leader.Name = "leaderstats"

    local amount = Instance.new("StringValue", leader)
    amount.Name = "yeahs"

    amount.Value = DS1:GetAsync(player.UserId) or 0
    DS1:SetAsync(player.UserId, amount.Value)
    amount.Changed:connect(function()
        print("Saving Data...")
        DS1:SetAsync(player.UserId, amount.Value)
        print(player.Name.."'s Data of "..amount.Value.." "..amount.Name.." has been saved.")
    end)
end)

game.Players.PlayerRemoving:Connect(function(player)
    print("Saving Data...")
    DS1:SetAsync(player.UserId, player.leaderstats.yeahs.Value)
    print(player.Name.."'s Data of "..player.leaderstats.yeahs.Value.." "..player.leaderstats.yeahs.Name.." has been saved.")
end)

And here is the script that gives the player "yeahs" (my game's currency):

    local yeahs = game.Players.LocalPlayer.leaderstats.yeahs
    local sound = Instance.new("Sound", game.StarterGui)
    sound.Name = "yeet"
    sound.SoundId = "doesntmatterfornow"
    sound.Looped = true

    sound.DidLoop:Connect(function(soundId, numOfTimesLooped)
        yeahs.Value = yeahs.Value + 1
        --print("number "..tostring(numOfTimesLooped))
    end)

    sound:Play()

The datastore script is stored in ServerScriptService and the script which adds yeahs to a player's total is in a screen gui as it is tethered to the intro I made for the game. (In case you need to know this.)

EDIT: Also the script which adds "yeahs" is a LocalScript and this place does has FE on.
