I created new Index like This

```
   POST times/available
    {
      "name": "Nursery one",
      "available": [
        {
          "number_places": 1,
          "date": "2018-04-01"
        },
        {
          "number_places": 1,
          "date": "2018-04-14"
        },
        {
          "number_places": 1,
          "date": "2018-04-30"
        },
        {
          "number_places": 1,
          "date": "2018-05-01"
        },
        {
          "number_places": 1,
          "date": "2018-05-24"
        },
        {
          "number_places": 1,
          "date": "2018-06-05"
        }
      ]
    }
My Query Like this
POST times/available/_search
{
  "query": {
    "match_all": {}
  },
  "script_fields": {
    "scoreee": {
      "script": {
        "lang": "painless",
        "source": """
            int total = 200;
            for (int i = 0; i < doc['available'].length; ++i) {
              total += doc['available'];
            }
            return total;
          """
      }
    }
  }
}

```

"reason" : {

          ],
          "script" : """

            for (int i = 0; i < 20; ++i) {
              total += doc['available.number_places'][0].value;
            }
            return total;

Hey,

you are not taking into account that `doc['available']` already is an array, so you cannot access the `number_places` field directly. Try `doc['available'][0].number_places.value` (on top of my head, untested)
