Help!

I need a have a header on every page AFTER my first page but:

I have two page breaks as i move from Portrait to Landscape then back to Portrait.

The header drops off the first page following each of the two page breaks. So all pages ok except for the twop pages following each break. If I insert the header into either one of these pages, it then appears on my first page (and I dont want it there...

Confused.....
