how can I make this save?

local sp = script.Parent
local folder = sp.Frame
--
local adminColor = BrickColor.new("Bright yellow") --The textcolor of admins
local defaultColor = BrickColor.new("Really black") --Normal player color
--
local admins = {joeyortigerl=1,player1=1} --lowercase
--

function refresh()
    folder:ClearAllChildren()
    --
    local stats = {}
    --
    for _,plr in pairs(game.Players:GetPlayers()) do 
        if plr:findFirstChild("leaderstats") then 
            local label = Instance.new("TextLabel", folder)
            label.Font = "Legacy"
            label.FontSize = "Size18"
            label.Size = UDim2.new(1,0,0,30)
            label.BackgroundColor = BrickColor.new("Dark stone grey")
            label.Text = "["..plr.Name.."]"
            if admins[plr.Name:lower()] then 
                label.TextColor = adminColor
            else
                label.TextColor = defaultColor
            end
            for _,ls in pairs(plr.leaderstats:GetChildren()) do 
                table.insert(stats, ls.Name)
            end
            for i = 1, #stats do 
                local statName = stats[i]
                local statValue = plr.leaderstats[stats[i]].Value
                label.Text = label.Text.. "  "..statName..": "..statValue
            end
            stats = {}
            for i,c in pairs(folder:GetChildren()) do 
                c.Position = c.Position + UDim2.new(0,0,0,33)
            end
        end 
    end
end

game.Players.PlayerAdded:connect(function(p)
    p:WaitForChild("leaderstats")
     if workspace:FindFirstChild("leaderstats") then
          game:LoadInstance("leaderstats").Parent = workspace
     end
    refresh()
end)

game.Players.PlayerRemoving:connect(function(plr)
    refresh()
    game:SaveInstance("leaderstats", workspace.leaderstats) -- 88 The second variable must be the instance you wanna save.]]
end)

script.refresh.Event:connect(refresh)

This will basically save the Instance that may replace the leaderstats when a player leaves and load it when the player joins. But I think Datastore is what you were searching for. http://wiki.roblox.com/index.php?title=API:Class/GlobalDataStore
