[LaTeX_monty]

Hi, I would like to split the nomenclature over two lines. I found a "code" for this at https://copyprogramming.com/howto/if-tw ... umns-latex
which states the following:

Code: Select all

Run LaTeX here

However, it does not compile mye desired outcome, as it states that something is wrong in line 23 and 24 with the "{" and "}" marks. I can not figure what is wrong. At the website you can see the desired outcome under "Solution" to question 2.
Any suggestions to this?
