do you have a reproducible example, or at least a full stack trace? Otherwise, it may get tough for us to track down the problem.

The first 8 characters of the root is a folder name. I want to group by folder name. I simplified the xquery to eliminate the collateral interactions, but still receive this error.

p.s. I was able to get bindings working using quotes:

open C4;set  QUERYPATH c:\dev\xq;set bindings "$date=20120507, $envir=PRD_Win"
