Which is exactly why I would defer to you two! I am pretty sure I am the

Agreed! I honestly don't know where the problem is and certainly should
not be offering "solutions" like I tried. This could simply be either a
documentation issue or a case of me not reading the documentation
carefully enough. At least, I was hoping that's what it was and someone
would tell me, "please just read this and this more carefully".
