     <programlisting role="php">
      <![CDATA[
<?php

<?php

    </example>

     You should see a progress bar like that :
     <figure>
      <graphic fileref="../media/screenshots/scratch1.png"></graphic>

    You've forgot to put the requires JavaScript code to manage the progress bar.
    <simpara>
     Adds the HTML_Progress::getScript or {@tutorial ui.getscript.pkg} method 
     between script-html-tags, and your code up and running look like:

    <example>
     <programlisting role="php">

  <title>The progress meter seems to be frozen at 100%, i see no changes </title>
  <para>
    Using {@tutorial progress.run.pkg} rather than coding a loop as in above example,
    you've forgot to give a delay to progress animation.
    <simpara>
     Because it's not necessary in real world, almost all cases, the delay is fixed at zero (default behaviour).
     Uses the {@tutorial progress.setanimspeed.pkg} method to fix the delay from 1 to 1000 milliseconds.
     In example below delay is only 0.5 seconds
    </simpara>
    <example>
     <programlisting role="php">
      <![CDATA[
<?php
require_once 'HTML/Progress.php';
$bar = new HTML_Progress();
$bar->setAnimSpeed(500);
?>
<style type="text/css">
<!--
<?php echo $bar->getStyle(); ?>
// -->
</style>
<script type="text/javascript">
<!--
<?php echo $bar->getScript(); ?>
//-->
</script>

<?php
echo $bar->toHtml(); 
$bar->run();
