Forcing a page break w Infomaker nested report

I have created a custom Infomaker report for subscription rollover. Because we needed two detail sections, I opted for two nested reports within a report to display this data.

Since the space on our pre-printed form only allows for four rows of detail in each of these detail sections, I adjusted the margins for these sub reports to only print four rows before breaking to a new page.

When I preview the sub report on its own in Infomaker, it breaks to a new page just like I want, but when I run the whole report, I only get one page with rows 1-4 on page 1 (which is what I want) but a second page is not created (not what I want; we lose a row which is not displayed at all).

Anyone have any ideas about this?

Thanks!
