Wow the keyboard shortcut approach worked! Fantastic!! I admit I had to Google your suggestion because I did not know what you meant by it, but I came across a very helpful site 10 Great Keyboard Shortcuts for Microsoft Word Styles Users



Attached is a document in which I played around a bit with the styles and explained what I had found. The issue seems to be with the ribbon pathway rather than with the Styles themselves. However, I created a new style using the “Create a style” option, which works fine! Does not produce an error!



I have googled "built-in name" etc. but have not quite yet figured out what that means, but for now I am happy that I can use my styles, although I will have to learn a new approach.



I would still like to be able to get rid of that problem, so if you and Charles can please continue applying your knowledge and skill set I will greatly appreciate it.



Thank you both for your time and energy and help so far.
