Sorry about the typo in my code, glad you got it working.

Nested repeaters need nested loops

Let’s say that the key for the repeater is field_123 and the key for the nested repeater is key_321

if (!empty($_POST['acf']['key_123']) && is_array($_POST['acf']['key_123'])) {
  foreach ($_POST['acf']['key_123'] as $row) {
    // nested repeater
    if (!empty($row['key_321']) && is_array($row['key_321'])) {
      foreach ($row['key_321'] as $sub_row) {
        $something = $sub_row['some-field-key'];
      }
    }
  }
}
