Hi Cheryl,
If you use a Section break as Graham suggests, you may find that you'll have to re-work the contents of the last two pages whenever
the document is edited, especially if you use a 'Next Page' Section break.
Another approach is to embed the header text in a field. To do this:
.. put double quotes at both ends of the header text (eg "header text").
.. select the header text and double quotes press Ctrl- F9 to create a pair of field braces around them. You should see something
like: { "header text"}
.. inside the left end of the fields, insert two more fields (via Ctrl- F9), thus: { { } { } "header text"}
.. fill in/around the fields, thus: {IF{PAGE}<> {NUMPAGES} "header text"}, being careful with the spacing.
.. when you're done, select the field and press F9 to update it.
Your header should now appear on all except the last page.
