Create a group in the subreport that is grouped on the value =1. This creates a dummy group. Move the column headers back to the subreport's new group header.
Suppress the report header of the subreport and use this group header as the report header. Because it's a group header, it has a Repeat Section property which you can set to Yes, and Access will repeat it at the top of each new page.
