Dynamic content on the master page

Hi All,

I have a simple problem. I have a master page with some header information almost all of which is fixed text. One piece of dynamic data does exist on the master page - the document number.

I've created a field in the master page which is bound to $.Agreement[].Customer[].DocumentNumber.

When the PDF is rendered in the browser, the first page has an document number as part of the header provided by the master page.

All subsequent pages have a header with the correct fixed text but the document number is blank. More strangely, when I save the PDF locally, the first document number is missing, but the one on page 2 is there.

Can anyone help populate all document numbers on all pages?

Cheers

Richard
