Data Stores don't seem to be working?

So I'm having troubles with data stores despite the print debugging method working fully through. There seem to be no errors in output either. The script is in a folder in ServerScriptService.

local DSService = game:GetService("DataStoreService"):GetDataStore("KytesSave")
local PlayersLeft = 0

game.Players.PlayerAdded:Connect(function(player)
    PlayersLeft = PlayersLeft + 1
    local Kytes = Instance.new("IntValue")
    Kytes.Name = "Kytes"
    Kytes.Value = 0
    Kytes.Parent = player
    local player_data
pcall (function()
    player_data = DSService:GetAsync(player.UserId.."-Kytes")
end)

if player_data ~= nil then
    Kytes.Value = player_data
else
    Kytes.Value = 0
end
end)

local bindableEvent = Instance.new('BindableEvent')

game.Players.PlayerRemoving:Connect(function(player)
    pcall(function()
        DSService:SetAsync(player.UserId..'-Kytes', player.Kytes.Value)
        print("Saved")
        PlayersLeft = PlayersLeft - 1
        bindableEvent:Fire()
    end)
end)

game:BindToClose(function()
    while PlayersLeft > 0 do
        bindableEvent.Event:Wait()
    end
end)
