 * What is wrong here? I followed some models already working but…
 *     ```wp-block-code
       //prova display price2 con IF
       $display_price2 = get_the_author_meta( '2_periodo', $post->post_author ). ' - ' . get_post_meta( $post->ID, "function_prezzo_secondo", true ). ;
   
       if ( ! empty( $display_price2)) {
   
       $display_price2='<div class="listino_prezzi">'. $display_price2 .'</div>';
       //fine prova
       ```

 * There’s an extra `.` operator at the end of the first assignment line that doesn’t
   belong. There could be other issues, but looking at code out of context makes
   it difficult to know.
 * Do you have `WP_DEBUG` defined as `true` in wp-config.php? Doing so will display
   error messages right on the page. Good for development, bad for production. The
   message ‘unexpected token “;” in path/filename on line _nnn_‘ would give you 
   a good clue on where and what to look for. Meaning something before the `;` is
   not as it should be. In this case it is immediately before. In other cases it
   can even be on a preceding line. Error messages are where PHP realized there 
   is an error, not necessarily where the error really is.
 * We’re happy to help you resolve coding problems when you’re unable to, but resolving
   on your own when possible will get your code working sooner 😉

 * besides the `.` I forgot the final bracket 🙂
 * I’m trying also to put a <strong>, I’ve tryed a lot of times but..nothing..here
   is my last try:
 *     ```wp-block-code
       $display_price2 = get_the_author_meta( '2_periodo', $post->post_author ). ' ' '<strong>'. get_post_meta( $post->ID, 'function_prezzo_secondo', true ). '</strong>' ' &euro;'.'/ sett.' ;
       if ( ! empty( $display_price2)) {
       $display_price2='<div class="listino_prezzi">'. $display_price2 .'</div>';
       }
       ```

 * Too may quotes 🙂 And unnecessary concatenation, though concatenation would be
   syntactically correct, it’s not necessary.
    `$display_price2 = get_the_author_meta('
   2_periodo', $post->post_author ). '<strong>'. get_post_meta( $post->ID, 'function_prezzo_secondo',
   true ). '</strong> &euro;/ sett.';` untested, but should be right… gotta run 
   right now.

 * 2 quotes were for displaying a blank space…just before `'<strong>'`

 * Include the blank space with the strong tag `' <strong>'`. While you could have
   used a another `.` operator to add the space, you should avoid concatenating 
   static strings together. Instead combine the strings into a single element. It’s
   not technically wrong to concatenate static strings, but it adds needless complexity
   and makes code more difficult to read.
