P.R.: I can't see anything wrong - you'd better post your data so we can try it. You might also try to upgrade to numpy 1.3.0, if you haven't already, I know there were some masked array changes between 1.2.1 and 1.3. -Jeff ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
