Interesting. Then I have more learning to do. The function is one
that I'm trying to move into an object oriented context and, given
your validation that the input is correct, what I'm finding is the my
method is doing the right thing for the wrong reasons while the
original function that has always worked is doing the wrong thing for
the right reasons. Enigmatic.

I may have to follow up on this thread, but I have to do my own due
diligence even to know what question to ask.

Thanks for your help.
