  • How about:

    function acf_prepare_field_set_print_max( $field ) {
    
    	$project_total_prints = get_field('project_total_prints');
    	$field['max'] = count($project_total_prints);
    	return $field;
    }
    add_filter('acf/prepare_field/name=print_nbr', 'acf_prepare_field_set_print_max');
