Re: ERT with cupbook.cls

[Holliday, Ian E]

OK - I sorted it out. It was of course simply that I'd tried to put ERT into a 
non-standard environment - paragraph - having forgotten that 'standard' is what 
I should normally use, and paragraph is a level in the section hierarchy. There 
have been a couple of others I noticed lower down the list that have also got 
caught with this one.
