This was it! It took me about eighteen tries and two hours of talking myself through it (I think all the staff outside my office thinks I'm going bonkers), but it did come together.
So I am assuming that if I wanted to do something really crazy, like add a Communication from a Reminder, I would just edit the formula in the "Add Communication" button of Reminders by extending this formula in the same pattern?
I did figure out reasonably early on (as in, last week), that I was best off duplicating my app and renaming it "Carrera's Test App." This lets me trial run edits and changes without creating a huge mess in my primary app, and minimizes any downtime that my reps have while actually using the app.
Thank you!
