your uniform page header willhave to be design in the page header section.
you would suppress the Report Header and footer
it sounds like you have no data or any grouping in the main report.
In that case I would use multiple detail sections, otherwise maybe a group header sections.
You have to watch adding sections to page headers (or page footers) as this section should never expand beyond one full page and using new page after on it. If you are using sub reports inisde page header sections that can expand beyond a page it will not work or print properly.
Using sub reports can be tricky as you have to understand and watch for the setting each section and each sub report to 'keep together' and new page before or after.
