 * Hello!
    I am a NOOB when it comes to writing functions for the functions.php 
   file. What I would like to do is to incorporate the “More to the Top” plugin 
   into a theme via the functions.php file.
 * Here is my code that is not working in my functions.php file:
 *     ```
       add_filter( 'the_content', 'moretothetop' );
   
       function moretothetop( $content ) {
       	global $post;
   
       	return str_replace( array( '#more-' . $post->ID . '"', '<span id="more-' . $post->ID . '"></span>' ), array( '"', '' ), $content);
       }
       ```
   
 * Can you help me figure this out?
 * Thanks!
