  • You don’t need that outside acf/init action to do this.

    Try this in your functions.php file (I changed the function name):

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