Help regarding a bash menu script
Greetings all,
I'm having some trouble writing a menu drive bash script, actually coding the menu part was not difficult however its a problem with a menu option I'm having trouble with.
My menu has 5 options, when the user selects the second option, they are then prompted to enter a number from 1-9 and depending on what number they entered the following output should be displayed

Code:
1
12
123
1234

i.e. they entered 4

now this seems like this should really not be that hard, but for the life of me can't figure it out...what I have so far is:::

Code:
#!/bin/bash
echo
echo "***********************"
echo "***********************"
echo
declare stop=0
while [ $stop == 0 ]; do
cat <<ENDOFMENU
1       : the first option
2       : the second option
3       : the third option
4       : the fourth option
5       : the fifth option
ENDOFMENU

echo
echo -n " Your choice? : "
read choice

...

case $choice in
  2)    echo -n " Now please enter a number 1-9 : "
        read number
        declare i=1
        while (( $i  <= $number )); do
                declare j=1
                while (( $j <= $number )); do
                        echo $j
                        printf $j + 1
                        (( j++ ))
                done
        (( i++))
        done

        declare stop=1
;;


which outputs:::
Code:
1
12
23
34
41
12
23
34
41
12
23
34
41
12
23
34
4

Any help would be much appreciated.

xmaddtopostfromlist

XmAddToPostFromList(library call)										 XmAddToPostFromList(library call)

NAME

       XmAddToPostFromList -- a RowColumn function that makes a menu accessible from more than one widget

SYNOPSIS

       #include <Xm/RowColumn.h>

       void XmAddToPostFromList(
       Widget menu,
       Widget post_from_widget);

DESCRIPTION

       XmAddToPostFromList makes a menu accessible from more than one widget. After a menu is once created, this function may be used to make that
       menu accessible from a second widget. The process may be repeated indefinitely. In other words, where an application would use XmCreatePop-
       upMenu  or  XmCreatePulldownMenu or their equivalent to create a new menu identical to one that already exists, it can use this function to
       reuse that earlier menu.

       If menu refers to a Popup menu, then the post_from_widget widget can now pop up the specified menu. The actual posting of the  menu  occurs
       as it always does, either through an event handler, or the automatic popup menu support (see the XmRowColumn(3) reference page).

       If  menu  refers  to  a	Pulldown menu, its ID is placed in the XmNsubMenuId resource of the specified post_from_widget.  In this case, the
       post_from_widget widget must be either a CascadeButton or a CascadeButtonGadget.

       Note that this function manipulates the internal structures themselves, not a copy of them.

       menu	 Specifies the ID of the RowColumn widget containing the menu (Popup or Pulldown) to be made accessible from the widget.

       post_from_widget
		 Specifies the widget ID of the widget which will now be able to post the menu specified by menu.

       For a complete definition of RowColumn and its associated resources, see XmRowColumn(3).
