Try:
$location = xprofile_get_field_data( 'Name of the Field', $EM_Person->ID, $multi_format = 'comma' );
		
	 
	
	
	
 
		
			
	
	
		
		Awesome! That did it! Thanks!
Here is my new code:
<?php
/* @var $EM_Event EM_Event */
$people = array();
foreach($EM_Event->get_bookings() as $EM_Booking){
        $people[$EM_Booking->person->ID] = $EM_Booking->person;
		$user_info = get_userdata($referring_user_id);
}
?>
        <ul class="event-attendees">
        <?php foreach($people as $EM_Person): ?>
        <li>
        <?php $user_info = get_userdata($EM_Person->ID);
        echo get_avatar($EM_Person->ID, 50) . " " . $user_info->first_name . " " . $user_info->last_name . " " . $location = xprofile_get_field_data( 'Ort', $EM_Person->ID, $multi_format = 'comma' )  ;
        ?></li>
        <?php endforeach; ?>
</ul>
		
	 
	
	
	
 
		
			
	
	
		
		Since I really like this code …

… I tried to implement your code-snippet into it. But since I’m not a programmer, I just can’t figure it out. So I’d be very happy if you could give me a hint 🙂
