Hi @jetro157,

I think the second one would be easier to achieve. If you only need to show the duration on the front-end, you can use the count() function on the repeater field. It should be something like this: count(get_field('repeater_field_name')).

If you need to show it on the backend, you can use acf/save_post to update the duration field using update_field(). Maybe something like this:

<?php

function my_acf_save_post( $post_id ) {
    
    $itinerary = get_field('itinerary_field_name');
    if ($itinerary){
        $duration = count($itinerary);
        update_field('duration_field_name', $duration, $post_id);
    }
    
}

// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 20);

?>

I hope this helps.
