break: cannot break

hi guys

I am working on a menu for linux... some basic stuff.

but I have an issue. I got 1 server where something is working and the same thing does not work in the same way in another linux box

Basically I am simulating a command line where user insert some commands and to end and go back to the previous menu that person has to press Control + C and Enter Key

all my server are centos 5.0

I am adding my menu here

basically you execute ./menu

After that go to option

9. Opciones
7. Ejecutar comando
and execute a command like pwd
after that
Press Control + C and Enter Key

but I got error ./menu: break: cannot break
but in other servers pressing Control + C and Enter Key goes back to previous menu

any idea how to fix that?
or another way to exit from that simulated command line and go back to previous menu where I selected 7. Ejecutar comando

Basically this is the part that has issues

Code:

##Shell simulada para ejecutar commandos 
ejecutacmd ()
{
header
echo -e "${bold}Press Control+C and Enter Key to go back to previous menu${offbold}"
echo -e " "
while true ; do
     read whichcmd?"Enter Command: "
     if [ $(sudo -l | grep -c "$whichcmd") -gt 0 ] ; then
          sudo $whichcmd
     else
          $whichcmd
     fi
done
}

menu (code) is attached so you can see all options
thanks a lot

Update
Uploaded as menu.txt just remove .txt and test it

mitem_value

mitem_value(3X) 														   mitem_value(3X)

NAME

       mitem_value - set and get menu item values

SYNOPSIS

       #include <menu.h>
       int set_item_value(ITEM *item, bool value);
       bool item_value(const ITEM *item);

DESCRIPTION

       If  you	turn off the menu option O_ONEVALUE (e.g., with set_menu_opts or menu_opts_off; see menu_opts(3X)), the menu becomes multi-valued;
       that is, more than one item may simultaneously be selected.

       In a multi_valued menu, you can used set_item_value to select the given menu item (second argument TRUE) or deselect  it  (second  argument
       FALSE).

RETURN VALUE

       The function set_item_value returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       E_REQUEST_DENIED
	    The menu driver could not process the request.

SEE ALSO

       curses(3X), menu(3X).

NOTES

       The header file <menu.h> automatically includes the header file <curses.h>.

PORTABILITY

       These routines emulate the System V menu library.  They were not supported on Version 7 or BSD versions.
