The print was just there as an example - what is done
with those values is actually a little more complex.
I like using quoted hash keys because they show up
better in the syntax-aware editor I use.
I did try this before I sent the message, but in the
original block of code. I think somehow in scaling
down the problem and taking it out of context I must
have eliminated the problem. I didn't try just before
I sent, I just confirmed that the structure that had
worked in the overall context worked without it.
Thanks & regards,
