Well.. I went back and recreated a new setup and sure enough.. this
time, it works both ways..  I dunno what I did.. I could almost have
sworn that the only thing I did was delete the ":" when it began
working.

I can almost picture seeing the statement that you _must_ use ":=" in a
variable assignment, and that there was a difference, but apparently I
dreamed it or it's a fact in some other application..  This belief was
what prompted the question.

Sorry for the noise, and thanks for the reply setting this straight.
