JavaScript, but you still need to test server side because this won't
work for every visitor. If it gets to page 1 with bad values,
regenerate the page with all but the bad values filled in, and a message
added indicating values to be corrected.

CGI.pm saves state. You'll probably be able to figure out what you need
from looking at the following pages:

http://www.foo.be/docs/tpj/issues/vol1_2/tpj0102-0004.html

http://www.perl.com/doc/manual/html/lib/CGI.html#SAVING_THE_STATE_OF_THE_SCRIPT_T

....and Google for "CGI.pm save state" for more.
