So you want the child to show the word count of the parent at the time of adding the note. Or do you want the current count.
Serendipitously, I just wrote a demo for another user who wants to show word counts - see here (demo file and lots of relevant aTbRef links).
As to pasting text into a container and it not firing the container’s OnAdd, I can’t replicate that. Until I have steps that reproduce the error, sadly I can’t help on that.
