Thanks, but I need to use the param function - these checkboxes are defined by data in a database - I can't pre-define them.

I hate to brute-force it, and not use CGI, which I can do, but I'd rather use CGI. But it's looking grim...

Update: Here's the brute force code that works:

 elsif ($type =~ /check/) {
            my $i=0;
            print "$english:\n";
            (my $values, my $labels) = split (':',$params[0]);
            my @checks_list = split (';',$values);
            my @clabels_list = split (';',$labels);
            foreach(@checks_list) {
                my $index=index $real_fields{$name},$_;
                if ($index != -1) {
                    print "$clabels_list[$i]<INPUT TYPE=\"checkbox\" N
+AME=\"$name\" VALUE=\"$_\" CHECKED>\n";
                } else {
                    print "$clabels_list[$i]<INPUT TYPE=\"checkbox\" N
+AME=\"$name\" VALUE=\"$_\">\n";

                }
                $i++;
            }
            print $q->br();
}

I'd love it if someone found a way to use the param function of CGI to get this to work!
