Silly me. After reading the help file for the upteenth time, my eyes are
open for the CalculateAllFields property. That's why it wouldn't calculate
using the AField parameter since it's null when this property is used.
Duh...

Apparently, setting this property to false was the last piece to the puzzle.
Everything now seems to work fine. I'll keep testing to make sure but it
looks like you steered my in the right direction, Helen.

Go back to the FB release notes. :)
