Leaderstats not showing up?

My leaderstats script doesnt seem to work. I've changed it several times, but no matter what I do, it won't work. If anyone can help me here it is:

local nshow = {"attack","strength","defense","fishing","smithing","fletching","cooking",
"woodcutting","crafting","theiving","prayer","farming"} --Different non-showing skills

--Load Data
game.Players.PlayerAdded:connect(function(player)
    player:WaitForDataReady()
    --Leaderstats
    leaderstats.Parent = game.Players:FindFirstChild(player)
    leaderstats.Name = "leaderstats"
    Level = Instance.new("IntValue")
    Level.Parent = leaderstats
    Gold = Instance.new("IntValue")
    Gold.Parent = leaderstats
    Skill = Instance.new("IntValue")
    Skill.Parent = leaderstats

    Gold.Name = "Gold"  
    Level.Name = "Gold"
    Skill.Name = "Skill"

    if not pcall(function() Skill.Value = player:LoadNumber("Skill") end) then
    Skill.Value = 0
    end
    if not pcall(function() Gold.Value = player:LoadNumber("Gold") end) then
    Gold.Value = 0
    end
    if not pcall(function() Level.Value = player:LoadNumber("Level") end) then
    Level.Value = 1
    end


    --stats
    local stats = Instance.new("Configuration", player)
    stats.Name = "stats"
    for _, stat in pairs(nshow) do
        stata = Instance.new("IntConstrainedValue", stats)
        stata.Name = stat
        stata.MinValue = 1
        stata.MaxValue = 99
        if not pcall(function() stata.Value = player:LoadNumber(stat.Name) end) then
        stata.Value = 0
        end
        Instance.new("IntValue",stata).Name = "xp"
        if not pcall(function() stat.Value = player:LoadNumber(stat.Name.."xp") end) then
        stat.Value = 0
        end
        Instance.new("IntValue",stata).Name = "nxp"


    end
end)

--Save Data
game.Players.PlayerRemoving:connect(function(player)
    player:WaitForDataReady()

    for i,e in pairs(nshow) do
        player:SaveNumber(e.Name,player.stats:FindFirstChild(e).Value)      
        player:SaveNumber(e.Name.."xp",player.stats:FindFirstChild(e).xp.Value)
    end

    player:SaveNumber("Skill",Skill.Value)
    player:SaveNumber("Gold",Gold.Value)
    player:SaveNumber("Level",Level.Value)
end)
