No need to be sorry, I just meant it is not an obvious error :slight_smile:

Does it works if You remove this?

  <div class="form-group">
    <%= label f, :id_medico, class: "control-label" %>
    <%= multiple_select f, :medico, Enum.map(@medico, &{&1.id, &1.nombre}) %>
    <%= error_tag f, :id_medico %>
  </div>
