Gracias, Sr. Collado, appreciate learning a new way to do it. I tend
to write tersely, and your method is likely easier for some to read.

As for everyone else, well, I have been asking a lot of questions

about asking for help with, I thought I would post my solution to my
problem, hoping it helps someone else.
