Subreport breaks (1 Viewer)

I have a report which has several subreports in it. If a subreport will not fit all on the same page, then I want it to break and start printing on another page. I have tried grouping to keep the whole group together on the same page to do that but it still breaks in the middle of the Immediate Family section (see the PrtRpt attachment).

The main report code can be viewed in the MainReport attachment. The individual subreport code for the section that's not breaking can be found in the SubRpt attachment. Does grouping within a report not work when it is added as a subreport to another report?

This is driving me crazy. Any ideas would be gratefully appreciated.

Two minutes after I made this post, I just tried adding the groups to the main report and putting the subreports inside the groups and the breaking finally worked. Please see my attachment (RevRpt) to see what I did. My apologies.

I love that moment when you can start to answer your own questions just by writing them out...
