how do I change the vertical ruler on page 2 of a letter

[Jackie]

I set my 1st page vertical ruler to start below my letterhead. When I try
to change the ruler on page 2 it also changes page 1. Help.

Margins are a section property; you can't change them for a single page
without inserting a section break, but you can fake a change. See
http://sbarnhill.mvps.org/WordFAQs/Letterhead.htm for the correct approach.
