Hi david,

I just was writing  to say that it doesn't seem to be working, but
before I posted I tried one more time.

I was selecting both of the outer curves as one set, and the bars as
another set, thinking that those were my regions.  But this time I
only selected the inner most curve of the outside "band" and now it
works.

Dumb me.
Thanks.
