Sub Report Page breaking issue

Migrateduser

<p>I'm having an issue where I have a sub report that isn't breaking up correctly.  My main table has data a few lines of data in it then at the bottom there's a sub table.  This sub table sometimes goes onto the next page if it has to much data to display.  If i manually enter a Page Break Interval of 6 the report splits up correctly with the sub table showing a few lines on the first page then continuing on to the second.  The issue is the sub table is dynamic so the hard coded value of 6 might not work the same for every instance.  Is there a way I can tell this sub table to split up when it hits the bottom of a page?  See attached for clarification (the Assignments area is the sub table).</p>
