Hi, Denny. Thanks for replying

It needs to be passed from the first defun, but I don't know the syntax
for doing that. The url-retrieve function is a little complex in terms
of its arguments. I think it's stumped even the experts on this list.

Thanks for bringing that up. Yeah, I followed that on your thread. I
might have to deal with that too. If, after I get the main part of my
code working how I want it, I find it's having that problem, I'll review
your emails (which I still have) and perhaps get back to you for some tips.
