Hi Susan.
These look like fun. I like your solution.
A couple of observations:
There’s no need to show the words as bold unless there is significance to the typeform.
You can place the opening Nemeth Code indicator on the same line as the closing transcriber’s note indicator.
Punctuate the words and the keyed abbreviations with a literary comma.
Make sure all your numbers are Nemeth numbers in the lower part of the cell. (There is a 1 and a 5 that need fixing)
I would move the problem to the left so the first cell of the separation line is in cell 1. This will give you more room for the comments.
