Richard,
You did take that from the 'Rat' book, but in the book
use CGI qw( standard );
Allows the author to use an implicit $q-> so he can write table
where as you need to write $q->table, $q->Tr, $q->td etc.

Or maybe you could write a simple sub that catches any anomolies at run time and
produces an Error message of your choosing. There is a good example of this in Chap. 5
of CGI Programming with Perl. You can also find the example from the chapter here:
http://examples.oreilly.com/cgi2/
Good
Try putting the following at the beginning of your script, it helps a lot
with debugging CGI:
use CGI::Carp qw/fatalsToBrowser/;
Instead of getting the usual Internal Server error, it displays the error in
your browser. Of course, make sure you have CGI first.

This is what you get when you run a CGI and the cgi terminated before
generating any valid output. Usually this happens if the perl script
doesn't compile and therefore doesn't run.
try 'perl -c
Anyone know what this means:
Premature end of script headers:
I found it in my server error log, after I got an internal server error
message when I tried to look at a new page I'd created.
