$mform->addElement('select', 'country', get_string('country','local_diary_module'), $choices, $purpose);
$mform->getElement('country')->setMultiple(true);
if (!empty($CFG->country)) {
$mform->setDefault('country', core_user::get_property_default('country'));
}
$mform->setDefault('country', $country);
