Hi Bill

thanks for looking at the code. Yes, I did not set the join to the table "vrnt".
(I had checked the query before against an informix sql server and it seemed to
be ok.) I have added the missing join. Surprisingly the query still does not run
or does not come to an end.

Regards
Thomas Vatter
