How come id will not pass through link? : <p>I have a simple link that needs to pass a variable through $_GET and set it to a variable in the page that is being opened. It is failing every time however and I am not sure why.</p>

<pre><code> &lt;a class='section_header' href='category/index.php?`id='" . $catid . "'&gt;&lt;b&gt;" . $row[0] ."&lt;/b&gt;&lt;/a&gt;
</code></pre>

<p>Code in category/index.php</p>

<pre><code>  $id = $_GET['id'];
  echo $id;
</code></pre>
