Huh? Aaah, sorry. I made a major search/replace-refactoring (that
obviously went wrong) on all open files in the editor before posting to
this newsgroup, and one of these files was my preparation of the queries

Sorry for wasting your time! :-(
However, your suggestion worked perfectly. Thanks a lot!
