Hi @jetro157,

I think you need to get the repeater fields first from the flexible field. Maybe something like this:

<?php

function my_acf_save_post( $post_id ) {
    
    if( have_rows('flexible_content_field_name', $post_id) ):

        $current_duration = intval(get_field('duration_field_name'));
        
        while ( have_rows('flexible_content_field_name', $post_id) ) : the_row();
            if( get_row_layout() == 'itinerary_layout' ):

                $itinerary = get_sub_field('itinerary_field_name');
                if ($itinerary){
                    $duration = count($itinerary);
                    $current_duration = $current_duration + $duration;
                }

            endif;
        endwhile;
        
        update_field('duration_field_name', $current_duration, $post_id);
        
    endif;
}

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

?>

Keep in mind that I haven’t tested it yet. Please fix the error message as needed.

Hope this helps.
