*sigh* that would be extremely complex. As you might note from looking at the URLs
which don't change (except for the occassional HTML get arguments), the code is
actually being summoned from a database based on state information in the hidden form
fields. Thus, all of the web pages are summoned from the same set of class files, the
sum total of which are rather large.
Here's the main class file. As you can see it doesn't follow the traditional
servlet->form->new servlet->new form. Also, I just don't expect people to have to
wade through a whole bunch of class libraries that I created myself.

The only suggestion I can make at this point is to post a URL to the servlet
source so that it can be looked at.

I'm not sure it is fault HTML. Are you setting the content type? Are you
trying to use compression?

That is the error reported for the Macintosh/IE combination. Does anyone know
why?
(Even with faulty HTML, I'd think the browser would still get faulty HTML
instead of nothing).

You might try looking at it in Mozilla. It looks totally wrong there.
When you type in an author first name and lastname, and hit submit you get a TOTALLY
blank page.

Hmm... for some reason I am getting a different set of output. This
is what I get:
<TR>
<TD><Input Type="CheckBox" Name="FACNO0000" Value="46464"></TD>
<TD>Straub Jr.</TD>
<TD>Detmar W.</TD>
<TD><A
HRef="http://readable.eci.gsu.edu:8080/examples/servlet/isbib?Command=Display&FromMenu=FacRes&MenuOption=1&No=0&Last=Straub
Jr.&First=Detmar W.">Change data</A></TD>
</TR>
This part of the code is auto-generated. What concerns me is that you
are getting eight zeros after the FACNO variable rather than four. Also note that the
code is "cleaner". I haven't made any changed to the code for at least a week.

You might try cleaning up the HTML and re-testing it. I ran it
through the HTML validator at validator.w3.org and got this:
* Line 23, column 64:
