how would i save multiple items in a folder?

function getitems(plr)
    local holder = game.ReplicatedStorage:FindFirstChild(plr.Name.."'s Items Holder"):GetChildren()
    for i,v in pairs(holder) do
        if v.ClassName == "StringValue" then
            if v.Name ~= "Value" and v.Value ~= "" then
                local id = game.Players:FindFirstChild(plr.Name).userId
                itemDataStore:SetAsync(id..":items", v.Value)
            end
        end
    end
end

    local getitems = itemDataStore:GetAsync(newplayer.userId..":items")
    if getitems == nil then
        print(newplayer.." Has No Items!")
    else
        local newitem = Instance.new("StringValue")
        newitem.Name = getitems
        newitemValue = getitems
        newitem.Parent = game.ReplicatedStorage:FindFirstChild(newplayer.Name.."'s Items Holder")
    end

im trying to save multiple values in a folder in replicated storage but this current script only saves 1 of those values not all of them. im pretty new to datastore and scripting in general. any help appreciated TY.
