The validation of values seems to work perfectly well, however, I wonder whether it is possible to require a field-entry to be a number AND to fall within a given range, e.g. between 0 and 10. I know how to get a number, I don't know how to
check for the range.

Hello Chris,

Below is the quick example I worked up. There is probably a more slick way of putting the requirements into the validate statement, but I've done it with additional JavaScript using the 'jsfunc' parameter.
Good luck, --bradoaks

use CGI::FormBuilder;

@fields = qw(age email mailing_list);
my $jsfunc = <<'EOJS';   # note single quote (see Hint)
   if (form.elements['age'].value >= 10) {
       alertstr += "Mr. T says, \"Age must be ten or under. Fool!\"\n";
       invalid++;
   }
EOJS

$form = CGI::FormBuilder->new(
            method => 'POST',
            fields => \@fields,
            validate => {
               email => 'EMAIL',    # validate fields using
               age => 'INT',     # built-in patterns
            },
            required => 'ALL',
            jsfunc => $jsfunc,
       );

$form->field(name => 'mailing_list',
            options => [qw/Subscribe Unsubscribe/]);

if ($form->submitted) {
   # you would write code here to act on the form data
   print $form->confirm(header => 1);
} else {
   print $form->render(header => 1);
}
