Michael, first, in spite of the goofed up time stamps on the Communities forum server that say 7 AM and 9 AM, thank you for being responsive at 4:30 in the morning my time which would be 2:30 your time! Guess we are both having short nights.
You've already helped me! What you said off-handedly has already helped me gain progress:
Still, I'm a little concerned about having to build and paste every time I want to test a change. The app might get quite involved at some point.
At least you've gotten me out of a complete rut.
Aside: I coded for 25 years. Then managed teams and coached Agile for 17 years. The last time I even touched code was 12 years ago. I'm a new Scaled Agile (SAFe) Coach at Bank of America now, and for me to blow all the dust and rust off my brain to try to code this functionality shows you how much I want this page. Sure appreciate your volunteering so much of your time and attention to my questions, sir. Blessings in your direction.
