I got it to work, you were right on target about the double-quotes. My
real problem was that I was simply pointing to the wrong thing.

My original block was reading
> update outer.reply {
>     User-Name := "%{reply:User-Name}"
> }

That returns empty, since the inner reply does not contain any User-Name
information. The correct block (which is working now) is:
> update outer.reply {
>     User-Name := "%{request:User-Name}"
> }

So, everything seems fine now.. Thanks all for your help, especially
Kalik.. :)
