Hello all,

I have, say, an index called X, a type called Y, and a field called number.  
There are 50 data.  
I want to calculate the sum of the values of each number field.

I tried this but it doesn't work :

```auto
    $numberSum= new \Elastica\Aggregation\Sum();
    $numberSum->setField('number');
    $numberSum->setName('NumberSum');

    $query = new Elastica\Query();
    $query->addAggregation($numberSum);

    $index = $client->getIndex('X');
    $buckets = $index->search($query)->getAggregation("NumberSum");

    var_dump($buckets);

```

I get this error, achats\_report is the index name :

```auto

Any idea what does it mean or what am I doing wrong?

I found the problem, I had to define the the type should be a number, I had it as a string. Thanks!
