Body Won't Shrink with Giant Sliding Field

[Shadowfax]

I have a report that's grouped by Hour and Segment, with all related discussions appearing underneath each timeslot (that is, in Body). However, because discussions tends to be pretty lengthy, that field's been sized to be very big yet 'shrinkable' via sliding.

Sounds good in theory, but in practice, something goes wrong. The list of discussions is always forced onto a new page! But if I shrink the Discussion field (and Body), the discussions correctly start appearing underneath the Segment again!

Why is this field (or part) not shrinking properly? The field obviously shrinks (the list of discussions looks fine), yet it's forced onto another page (as if something isn't shrinking).

Suggestions? Explanations?

The problem is with the SEGMENT sub-summary. The field "Sched_SegmentNumber" is not set to do any sliding, thereby effectively shortening the remaining available page space.

Set it to sliding up/all/reduce

Sweet! Thanks for the help IdealData, that was just what I needed.
