I have Word 2003.

Whenever I do number indetns, I would like items 10, 11, 12, etc. to line up
in such a way that their units digit lines up with the numbers 1 through 9.
For example,
                                9. nnn nnn nnn            
                              10. mmm mmm mmm           (1)
                              11. lllllll lllll kkkk

As it is now, the tens diging lines up with the numbers 1 through 9:

                               9. kkk kkk lll
                               10. mmm mmm mmm             (2)
                               11. jjj jjj jjj

How can I make the numbering line up as shown in the example (1)?

Thank you.
