$_SESSION doesn't work properly
<p>Does anybody know why the following code doesn't work properly?</p>

<pre><code>function LinksPage()
{
    $ClickedWord = $_GET['clickedword'];
    foreach($_SESSION['Links'] as $key=&gt;$value)
    { 
        if ($key == $ClickedWord)
        echo $key."  ".$value.' &lt;br /&gt;';
    }
}
</code></pre>

<p>When I check <code>$ClickedWord</code>, <code>$_SESSION['Links']</code>, I see that there is a key in <code>$_SESSION['Links']</code> that matches <code>$ClickedWord</code> but when I run the program if doesn't generate output.</p>
