I don't know exactly how your script is intended to work, but I wrote an example script to demonstrate traversing hierarchical menu choices. Maybe it will help (no guarantees that you can't break the script; it makes assumptions).

Code:

#!/usr/bin/ksh
# The quick brown fox jumps over the lazy dog

set -A animalname "fox" "dog"
set -A foxadject "quiet brown" "quick brown" "lazy brown" "quick red" "red slow"
set -A dogadject "slow" "quiet" "sleeping" "lazy" "brown"
set -A action "jump" "run" "skip" "hop" "roll"

until [[ -n $animal && -n $foxadj && -n $dogadj ]]
 do
  clear
  choice=1
  print "\nPlease select an animal.\n"
  select animal in ${animalname[*]}
   do
    choice=2
    print "\nPlease select a description for the $animal.\n"
    case $animal in
      fox)
        select foxadj in "${foxadject[@]}"
         do
          break $choice
        done
        ;;
      dog)
        select dogadj in "${dogadject[@]}"
         do
          break $choice
        done
        ;;
    esac
    break $choice
  done
done

until [[ -n $verb ]]
 do
  print "\nPlease select an action.\n"
  select verb in "${action[@]}"
   do
    break
  done
done

print "\nThe $foxadj fox ${verb}s over the $dogadj dog.\n"

install-menu(1) 					      Debian GNU/Linux manual						   install-menu(1)

NAME

       install-menu - Process a menu method and generate the menu files for a window manager or a menu-aware application.

DESCRIPTION

       update-menus(1) computes the list of menu entries and passes it in turn to the menu methods in /etc/menu-methods/. The task of a menu meth-
       ods is to generate menus for a specific window manager.	install-menu provides a generic and customizable way to do that. The documentation
       of the install-menu definition language is available in the Debian Menu manual, a local copy being available in /usr/share/doc/menu/html.

SYNOPSIS

       install-menu [-vh] [--remove] <menu-method>

       Read menu entries from stdin in update-menus --stdout format and generate menu files using the specified menu-method.

       Normally used in menu method scripts as #! /usr/bin/install-menu.

OPTIONS

       -h,--help
	      Show the help message and exit.

       --remove
	      Remove the menu files instead of generating them.

       -v,--verbose
	      Output messages about what the program is doing.

COPYING

       install-menu is distributed under the term of the GNU General Public License version 2, or (at your option) any later version.
