Painless supports `for` loop, so you can easily iterate over your array of values. You would need to do something like:

```auto
int count = 0;
for (val in doc['sendSMS']) {
  if (val == true) {
    count++;
  }
}
emit(count);

```

Thanks for your answer, but when i try your script, i have an error : "reason": "Unknown call [emit] with [1] arguments."

But I can't solve this error...

Do you have an idea please?

Have you tried `return`?
