Using Folders for Datastore?

I've attempted this and I'm not sure if I am close or not. The script doesn't work. I was just playing with it at the beginning now I want to learn how to fix this so it works.

function CreateData(Player)
if Data[Player] == nil then
    for i,v in pairs(Player.Leaderstat:GetChildren()) do
        if v.ClassName == 'Folder' then
            Data[Player][""..v.Name] = CompileData(v)
        elseif v.ClassName == 'IntValue' or v.ClassName == 'StringValue' then
            v.Value = Data[Player][""..v.Name]
        end
        if v.ClassName == 'IntValue' then
        Data[Player][""..v.Name] = 0
        elseif v.ClassName == 'StringValue' then
            Data[Player][""..v.Name] = ""
        end
        end


function CompileData(Player, t)
    t = Data[Player] or {}
    for i,v in pairs(Player.Leaderstat:GetChildren()) do
        if v.ClassName == 'Folder' then
            Data[Player][""..v.Name] = CompileData(v)
        elseif v.ClassName == 'IntValue' or v.ClassName == 'StringValue' then
            v.Value = Data[Player][""..v.Name]
            end
        if v.Name ~= "Type" and v.Name ~= "Type2" then
        v.Value = Data[Player][""..v.Name]
        elseif v.Name == "Type" or "Type2" then
        end 
    end
    return(t)
        end 
    end
end

function LoadData(Player)
 if PlayersLoaded[Player] == nil then
    Data[Player] = DSS:GetAsync(""..Player.UserId)
    function CompileData(Player, t)
    t = Data[Player] or {}
    for i,v in pairs(Player.Leaderstat:GetChildren()) do
        if v.ClassName == 'Folder' then
            Data[Player][""..v.Name] = CompileData(v)
        elseif v.ClassName == 'IntValue' or v.ClassName == 'StringValue' then
            v.Value = Data[Player][""..v.Name]
            end
    end
    return (t)
        end
    end

game.Players.PlayerAdded:connect(function(Player)
    game.ReplicatedStorage.Leaderstat:Clone().Parent = Player
if DSS:GetAsync(Player.UserId) == nil then
    CreateData(Player)
elseif DSS:GetAsync(Player.UserId) ~= nil then
    LoadData(Player)
    end
end)

game.Players.PlayerRemoving:connect(function(Player)
    DSS:SetAsync(""..Player.UserId, Data[Player])
end)
