I have two subforms, one on top of the other. The second one is marked Keep with Previous in the Pagination tab.
Yet page breaks are allowed to occur between the two, leaving the one orphaned at the bottom of a page.
Anyone know what I'm missing?
Yes, "on top of the other" referred to the hierarchy.
Your point on sibling subforms was what I was missing.
Not sure what you mean by "one on top of the other", maybe a screen shot of the hierarchy would help.
The "Keep with Previous" option will only work with sibling subforms.
