   I'm using this code to get custom field values from subpages:

   <?php
   $args = array(
   'post_type' => 'page',
   'post_status' => 'publish',
   'post_parent' => $post->ID
   );
   $my_query = null;
   $my_query = new WP_Query($args);
   if( $my_query->have_posts() ) {
   while ($my_query->have_posts()) : $my_query->the_post(); ?>
   <p><?php echo get_post_meta($post->ID, 'Email', true); ?></p>
   <?php endwhile;
   }
   wp_reset_query();
   ?>

   This way I got this output:

   <p>email 1</p>
   <p>email 2</p>
   <p>email 3</p>
   <p>email 4</p>

   I would like to know how to get a comma separated output like this one:

   <p>email 1,email 2,email 3,email 4</p>

   This is untested, but should be close:

   if( $my_query->have_posts() ) {
      $sep = '';
      $list = '';
      while ($my_query->have_posts()) : $my_query->the_post();
         $item = get_post_meta($post->ID, 'Email', true);
         if ($item) {
            $list .= "$sep$item";
            $sep = ', ';
         }
      endwhile;
      echo "<p>$list</p>";
   }

   You could also use this:

   if( $my_query->have_posts() ) {
      $list = array();
      while ($my_query->have_posts()) : $my_query->the_post();
         $item = get_post_meta($post->ID, 'Email', true);
         if ($item) $list[] = "$item";
      endwhile;
      echo "<p>" . implode(',',$list) . "</p>";
   }

   Thanks a lot!
   It works perfectly :-)

   One more question: if I wanted to do the same stuff but getting custom field values from sub-subpages what should I change?

   The code should work the same if you use the sub-page ID as the post_parent.

   I finally had time to try it and that's the code:

   $parent = $post->ID;
   $args = array(
       'post_type' => 'page',
       'post_status' => 'publish',
       'child_of' => $parent
   );
   $pages = get_pages($args);
   if ($pages) {
     foreach($pages as $post) {
       setup_postdata($post);
       if ($post->post_parent != $parent ) {
         $item = get_post_meta($post->ID, 'Email', true);
         if ($item) $list[] = "$item";
   }
   }
      echo "<p>" . implode(',',$list) . "</p>";
   }

   Thanks a lot for your help!
