================================

<HTML><HEAD><TITLE>Exercise 1</TITLE></HEAD>
<BODY>
<H1>
<P>Compilation of Part I Exercises</H1>
<HR>

<SCRIPT language=JavaScript>
refresh=date.lastModified();
now=new Date();
deadline=new Date("July 08 2006 00:00:00");
document.write("<h2><p>I worked on this date: " + refresh + "<p></h2>");
time_remaining=(((deadline - now)/1000)/60)/60; //hours
document.write("<p>Time remaining to complete this course: " + time_remaining + "<p>");
</SCRIPT>

Hi there xxhe,

and a warm welcome to these forums.

this...

Code:

refresh=date.lastModified();

...should be...

Code:

refresh=document.lastModified;

Note that language="JavaScript" is a deprecated attribute, use type="text/javascript" instead.
It is also advisable to use a DOCTYPE as a matter of habit.

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Exercise 1</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>

<h1>Compilation of Part I Exercises</h1>

<hr>

<script type="text/javascript">
<!--

  refresh=document.lastModified;
  now=new Date();
  deadline=new Date("July 08 2006 00:00:00");
  time_remaining=(((deadline - now)/1000)/60)/60; //hours

  document.write("<h2>I worked on this date: " + refresh + "<\/h2>");
  document.write("<p>Time remaining to complete this course: " + time_remaining + "<\/p>");

//-->
</script>

<hr>

</body>
</html>

The  around the javascript can result in it being treated as comments by the latest browsers and document.write isn't supported by XHTML (the successor to HTML).

From the look of the code that book is several years old and way out of date. The latest version of Javascript is 1.6 and there have been lots of changes over that time especially as to how to interact between Javascript and the content of the web page - especially the way you can manipulate the way the page looks by updating the stylesheet.
