I actually have the book as well ('Official Guide to Programming with

I have a feeling that a hash can't be passed this way. Arrays and
strings are no problem, but I believe the CGI protocol does not allow
passing complex data structures like arrays of hashes, or hashes of hashes.
You are correct that CGI does not allow you to pass HoH structures
directly; however, you can use Storable.pm to convert a HoH into a
string that can be made the value of a form element (after it's been
HTML-encoded).
Sessions are an even better idea for passing complex data between CGI
programs written by the same author. Investigate the docs for
CGI::Session and Apache::Session (if you're using Apache).
