problem of PHP automatically numbers
<pre><code>&lt;?php 
    $result = mysql_query("SELECT * FROM articles WHERE tag='sports'"); 
    $strss=$strss+1;
         while ($row = mysql_fetch_array($result))
             {
         echo '&lt;li id="nav'.$strss.'"&gt;&lt;a href="#" &gt;'.$row['title'].'&lt;/li&gt;';
             }
?&gt;
</code></pre>

<p>Why I can not set a automatically numbers? the number always is <code>1</code></p>
