Word 2007

I am trying to duplicate a table of contents. The format is as follows:

Article One Identifying Properties.........................1-1
Section 1.01 Size.............................................. ...1-1
Section 1.02 Color............................................. ..1-2

Article Two Location Specimen


-----------------------------------
If I multi-line numbering on headings. How do I get the Section numbers to left justify
and the 20 spaces before the subheadings start and then right justify?

Do I need a new version of Word?


Thanks in Advance.
