How to force a page break in 1st subreport based on info in 2nd or 3rd subreport

[SallyJenkins]

I have created a main report that is grouped by account id. Within the group account ID footer section there are 3 subreports. The main report and subreports are printing the correct information. My 1 big remaining problem is how to print a conditional page break before the 2nd and/or 3rd subreports. Here's the deal. There will always be data for the 1st subreport; it will always print. The 1st subreport will always print on the 1st page of the report along with the detail information. The 2nd and 3rd subreports may or may not have data. The objective is to print the 2nd and/ or 3rd subreports on a new page if one or both have data.
Let me know if I should attach a report sample, or ???
Many thanks, S
