Struggling with styles and table of contents in 2007

[ArielZusya]

I'm pulling my hair out on this one. Here's my trouble. I want to create a
documents with some basic outline structure:

I.
A.
1.
i.
a.
1.
i.
a.
1.

I later want the document to be able to automatically generate a table of
contents. I decided to use the Heading styles to control how this will all
look later. I set Heading 1 to be numbered using I. and to start at 0" from
the left margin but have a hanging indent of .25". I further, stripped the
funky formatting that seems to be the default for heading 1 and changed it to
Automatic for color, 12pt Times New Roman no bold or italics, and set the
line spacing to zero. I then went in to Heading 2 and did the same only
changed the left margin to .25" and the number to A. I also set Heading 2 to
be based on Heading 1. I'm not sure if that's necessary but I noticed that if
I tried to have the program do all of this itself it always did that. I did
the same with Heading 3 changing the left indent to .75 and so on through
Heading 9.

Everything looked great until I noticed that the heading 4 under the second
instance of heading 3 didn't have it's numbering restarting at 1. in other
words:

I.
A.
1.
i.
ii.
iii.
2.
iv.
B.
3.
2.
C.
etc.

If I told the program to restart the numbering at 1 it ignored all the other
formatting that I so painstakingly implemented. I decided to ignore that
problem, finish inputing the data, and then go back to the style profiles and
fix it there. When I made the adjustment in the style profile it randomly
changed parts and not others. What am I doing wrong? I can't seem to see a
logic in all of this and I'm getting really frustrated. Please help! Thanks!

Did you do all the assigning of numbering-style and indenting under
the List Format panel of Heading 1? (You need to identify your version
of Word to get step-by-step directions.)
