Thanks for the additional clarification and thanks in particular for revealing that there is an extensive User Guide available at the link you provided (index.htm)!
How would I have found that User Guide? Upon purchase, I had originally gone to My Account | Your Account | CSS Form Builder and reviewed all available links. I just did that again and I am unable to locate a link to this (extensive) User Guide!
How would I have found this guide and, since I've purchased quite a few other extensions, how would I find similar User Guides for my other extensions. If they are as extensive as the one for CSS Form Builder they would be a "gold mine" of useful info!
