Tried to find this in a previous question, but couldn’t locate it:
Is there a way to get Chapter names and/or numbers automatically included in headers or footers after compile?
Thanks.
You can do this via tags. This thread might help…
Section 24.22.1 of the user manual has more info.

Headers are impacted by the compile format. Depends on what you are compiling to.
I’m proofing in WORD. Your “<$sectiontitle>” technique worked – thank you very much! 
Glad it worked. Good luck with the work.
