Yes, your sentances would be cut in half as you have closed your speech marks half way through the phrase.
2 - I dont think that you can have an open <BR> within a script like that:

try this instead:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<HTML>
<HEAD>
<TITLE>Write</TITLE>
<SCRIPT LANGUAGE="JAVASCRIPT" TYPE="TEXT/JAVASCRIPT">
<!--
document.write("hey<BR>")
document.write("Joe said, \"Hi, how are you doing?!\"<BR>")
document.write("Angel said, \"Good, thanks! is this your new car?\"<BR>")
document.write("Joe said \"Yeah, that\'s mine!\"")
//-->
</SCRIPT>
</HEAD>
<BODY>
</BODY>
</HTML>

First of all, you have no DTD (doctype), which must be included in all documents. Second, your HTML is not valid and makes use of JavaScript without providing alternative text or data for those without JavaScript enabled on their user agents (browsers). Your code should be as follows:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
&nbsp;"http://www.w3.org/TR/html4/stirct.dtd">
<HTML lang="en-US">
<HEAD><TITLE> Time </TITLE>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<SCRIPT type="text/javascript"><!--
var dt=new Date();
dat1= (dt.getMonth()+1)+"/";
dat2= dt.getDate()+"/";
dat3= dt.getYear();
newDate= dat1+dat2+dat3;
//--><SCRIPT></HEAD>
<BODY>
<p>This is the information that anyone and everyone will see on the page.</p>
<script type="text/javascript"><!--
document.write("<p>");
document.write("<h1 style=\"font-size:18px;\">"+newDate+"</h1>");
document.write("<H2 style=\"text-align:center;\">This document was last modified "+document.lastModified+"</h2>");
document.write("<h4 style=\"text-align:center;\">This page is still under construction</h4>");
document.write("This is the paragraph that only users with JavaScript enabled will see.</p>");
//--></script></BODY></HTML>

I need to make a note not to copy and paste people's original code... The first line that shows stirct.dtd should be strict.dtd

Thanks, fredmv.

No problem; simple typos are among the hardest errors to find. I also fixed the typo in the DTD. ;)
