I use InDesign CC 16.1.
I have a ~200-page InDesign book with about ninety short chapters. I have divided the book into parts. Each such part begins with a one-page document that has a single line of text in it, styled as a "Part Title". The "Part Title" paragraph style uses the following numbering options:
A part title page looks like this (which is how I want it):
I set Document Chapter Numbering to "Same as Previous Document in the Book", so that the part title page won't increment my chapter counter.
What I do not know how to do is insert the most recent Part Title text from the book into the running header of the chapters in my book. I know how to define a text variable:
But the problem is, the variable's value is empty whenever I try to refer to it, either in the body of my chapter text, or in a running header. I presume this is because no chapter actually has a Part Title in it (my Part Title paragraphs are only on non-chapter part title pages).
My question is: How can I insert the Part Title name into my running headers?
Bonus question: How can I also insert the Part Title number into my running headers?
