   i try to follow this wordpress wiki http://codex.wordpress.org/Function_Reference/get_page
   for put on my home page the excerpt of some post, with this code i put on my home page the content

   <?php
   $page_id = 424;
   $page_data = get_page( $page_id );
   $content = $page_data->post_content;
   $title = $page_data->post_title;
   echo $page_data->post_content;
   ?>

   then with (theorically) I put the excerpt on the home page, but nothing,

   <?php
   $page_id = 424;
   $page_data = get_page( $page_id );
   $content = $page_data->post_content;
   $title = $page_data->post_title;
   $excerpt = $page_data->post_excerpt;
   echo $page_data->post_excerpt;
   ?>

   where is the mistake?the function is in the codex so it should go :(

   Does the page have an excerpt entered into the excerpt field?

   If there's nothing in the excerpt field for that page, you'll see just that, nothing!.. :)

   You could use something like this instead..
   

   <?php global $post; $myposts = get_posts('post_type=page&include=424'); ?>
   <?php foreach( $myposts as $post ) : setup_postdata( $post ); ?>
       <?php the_excerpt(); ?>
   <?php endforeach; wp_reset_query(); ?>

   http://codex.wordpress.org/Template_Tags/get_posts

   Using get_posts() and setup_postdata() should allow the use of the_excerpt() which will return content even if you've not used the excerpt field.. ;)

   NOTE: Despite the name, get_posts() can return any post_type, not just posts.. (and it supports more parameters then the get_page eqivalent).

   yes i create an excerpt field with some word but nothing, your code is perfect, now I have to add the possibility to have random subpage of a page.
   I don't know that get_post return also page, i think that return only posts, thank you very much!

   excuse me for my bad english :)

   add this code in your functions.php
   

   add_filter('wp_trim_excerpt', custom_excerpt);
   function custom_excerpt($text) {
     $text = str_replace('[...]', '<a href="' . get_permalink() .'">..complete post</a>', $text);
     return $text;
   }

   In WP 2.9+ you can use excerpt_more instead of wp_trim_excerpt:
   

   add_filter('excerpt_more', 'custom_excerpt');
   function custom_excerpt($custom) {
   	return '<a href="' . get_permalink() .'">..complete post</a>';
   }
