Help Debugging this code ,error in Log.i();

Hi! i keep getting an error and i believe it to be in the log.i() line. Any assistance will be highly appreciated. // JSONObject 'jsonData' was loaded from data.jsonJSONArray jsonBooks = jsonData.getJSONArray("books"); String name = jsonData.getString("name"); String publisher = jsonData.getString("publisher"); String language = jsonData.getString("language");

JSONArray jsonBooks = jsonData.getJSONArray("books");

for(int i = 0; i < jsonBooks.length(); i++){ JSONObject jsonBook = jsonBooks.getJSONObject(i); int pages = jsonBook.getInt("pages"); Log.i("CodeChallenge", "title" + ", " + pages); }

// JSONObject 'jsonData' was loaded from data.json

The problem you are having is that you are using the string title not the book title. You need to change the last line of your for loop where it creates the string in the Log to the code below:

(basically reference the book title by creating a new string variable and assigning it the book title and use that)

```String name = jsonData.getString("name"); String publisher = jsonData.getString("publisher"); String language = jsonData.getString("language");

JSONArray jsonBooks = jsonData.getJSONArray("books");

for(int i = 0; i < jsonBooks.length(); i++){ JSONObject jsonBook = jsonBooks.getJSONObject(i); int pages = jsonBook.getInt("pages"); String title = jsonBook.getString("title"); Log.i("CodeChallenge", title + ", " + pages); }```

Hope this helps Daniel
