Code challenge NOT passing

This code challenge is pretty easy and self explanatory but for some reason challenge 2/2 will not pass me even though the results are correct.

Error: Bummer! Your loop should run three times and call 'getJSONObject()' each time through.

My code:

// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("jsonData");

for(int i = 0; i < jsonShows.length(); i++){
  JSONObject data = jsonShows.getJSONObject(i);
  Log.i("CodeChallenge",  data.getString("title"));
}
CodeChallenge.java
// JSONObject 'jsonData' was loaded from data.json
JSONArray jsonShows = jsonData.getJSONArray("jsonData");

for(int i = 0; i < jsonShows.length(); i++){
  JSONObject data = jsonShows.getJSONObject(i);
  Log.i("CodeChallenge",  data.getString("title"));
}
data.json
{
    "name":"Netflix Playlist",
    "shows":[
        {
            "title":"Doctor Who",
            "season":8,
            "episode":3
        },
        {
            "title":"Arrow",
            "season":1,
            "episode":10
        },
        {
            "title":"Portlandia",
            "season":4,
            "episode":5
        }
    ]
}

Hi Lucas,

Challenge 1 shouldn't have passed, as it looks like the problem is in the first line of code. You're looking for "jsonData" from the jsonData, but you need to be looking for "shows" in jsonData.

Hope that helps!
