unexpected comma error message
<p>I don't understand why I am getting the following error:</p>

<blockquote>
  <p>[Sun Apr 10 21:29:31 2011] [error]
  [client 127.0.0.1] PHP Parse error: 
  syntax error, unexpected ',' in
  /var/www/pay_registration_fee.php on
  line 105, referer:
  <a href="http://localhost/pay_registration_fee.php" rel="nofollow">http://localhost/pay_registration_fee.php</a></p>
</blockquote>

<p>line 105 is:</p>

<pre><code>$STH-&gt;bindParam( ':users_id', $users_id), PDO::PARAM_INT, 1 );
</code></pre>

<p>users_id is:</p>

<pre><code>$users_id = $_SESSION['LoggedIn'];
</code></pre>

<p>$_SESSION['LoggedIn'] is:</p>

<p>1</p>
