Hi David
If you want the header on page 1 only, then you can do this by changing the
Page Layout settings to 'Different First Page'. This will create a new blank
header on page 1, so you will need to cut and paste the header from the
later pages to the first page header.
If the header has to reappear on page 5, after a gap, you will need to use a
section break. In the section following the break, unlink so that the header
is not 'Same As Previous', and then paste the header into place again.
Hope this helps
