MIT APP INVENTOR 2词典出现问题

Question

MIT APP INVENTOR 2 I have this problem: I have a dictionary with many sub-classes. But I have no idea how I could access to specific data inside the dictionary. For example a have the next list:

{
  "keystatus" : "valid",
  "status" : 0,
  "result" : [
    {
      "stores" : {
        "0" : {
          "category" : "",
          "min_price" : "64.90",
          "manufacturer" : "adidas",
          "url" : "https:\/\/www.rakuten.de\/%20produkt%20\/adidas-leonero-herrenschuhe-sneaker-2040331525.html?portaldv=6",
          "title" : "adidas Leonero Herrenschuhe Sneaker",
          "advertiser" : "Rakuten Deutschland GmbH",
          "currency" : "€",
          "max_price" : ""
        }
      },
      "details" : {
        "barcode_formats" : "EAN 4058025901204",
        "color" : "",
        "publisher" : "",
        "weight" : "",
        "actor" : "",
        "brand" : "adidas",
        "product_name" : "adidas Leonero Herrenschuhe Sneaker",
        "category" : "",
        "prod_details" : "",
        "manufacturer" : "adidas",
        "length" : "",
        "label" : "",
        "clothing_size" : "",
        "artist" : "",
        "height" : "",
        "model" : "",
        "width" : "",
        "director" : "",
        "genre" : "",
        "manufacturer_part_number" : "Adidas Leonero",
        "long_description" : "Nach 70 Jahren als einer der weltbesten Hersteller von FuBballschuhen hat adidas jede Menge Erfahrung gesammelt, wenn es um cleanen Sportstyle geht. Wir haben uns von einigen der legendärsten Designs aus unseren Archiven inspirieren lassen und m",
        "features" : "",
        "author" : ""
      },
      "reviews" : {

      },
      "type" : "EAN",
      "images" : {
        "0" : "https:\/\/images.barcodelookup.com\/9152\/91526482-1.jpg"
      },
      "barcode" : "4058025901204"
    }
  ]
}

I want to access to this part of the dictionary ["result"][0]["stores"]["0"]["title"] . Any thoughts?

All ideas are welcome. Thanks
