Hi Evan & zope-dev'ers, Hope you can help, and pre-emptive apologies for the bad mood I'm in :-S I want to do: try: acatalog.searchResults(aDict) except CatalogError,e: print "Something bad happened: ",e Where should I import CatalogError from? And _please_ don't tell me I have to go through some convoluted security process to do this :-( cheers, Chris
