Can't tell from your response what isn't working. We need to know the exact layout of the report. Right now, I'm guessing that you have grouped on work order and the last group shows the work order with details and appears on (TotalPagecount - 2), followed on the next page (next to last) by a group footer, where you want the page header, followed by a blank page. But this is all a guess! Please enlighten us so we can help! Also, it will be easier to help if you explain what happened when you tried previous solutions that did not work.
