local datastoresev = game:GetService("DataStoreService")
local AbilityStore1 = datastoresev:GetDataStore("AbilityStore1")

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local Ability = Instance.new("StringValue")
    Ability.Name = "Ability"
    Ability.Parent = leaderstats


    
    AbilityStore1:GetAsync(player.UserId)
    -- Load--
    local success, errormessage = pcall(function()
		         data = AbilityStore1:GetAsync(player.UserId)
		print("Loading Data")
    end)

    if success then
		Ability.Value = data[1]
