Vojo: Could you be a little more specific and only include some solution that you have, in fact, used. Please test a solution before you post. Thanks, so much, for your input.
Hyogapag: I am wondering if something might be wrong with my edition of LibreOffice. If I follow your suggestions I get no page numbers at all. Equally puzzling is that if I enter a simple page number field, nothing happens. There is no page number entered on subsequent pages.
The solution that you suggest, did you actually test it in the software with positive result?
Additionally, if I use the page number function on Calligra (which I downloaded… looking for solutions to this simple document creation problem), nothing happens. Additional pages are unnumbered.
I do believe in open source software. My belief would be increased if said software functioned.
Creating a document, in this case auto numbered invoices with a number starting with something like 1739, in MS Word has never been a problem. I suppose a hand crank solution is to manually number invoices as they are created in the document. We use software to solve these kind of problems. In good software those solutions work.
