Why I am still not getting this code done?
<p>I already tried changing quotes, dots, but still getting a error. Can't find the mistake!</p>

<pre><code>$Title .= '
        &lt;meta property="og:description" content="&lt;?php
  if ( function_exists('wpseo_get_value') ) {
    echo wpseo_get_value('metadesc');
  } else {
    echo $post-&gt;post_excerpt;
  }
?&gt;"/&gt;
    ';
</code></pre>
