I'm trying to add a second value column that uses the last() function. PB lets me save the crosstab definition, but if I try and run the app using this definition, or when I close and re-open the datawindow in the dev environment, I get a GPF. Using the count() method seems to work fine. Is there a known issue with the first/last/min/max methods (tried 'em all) in crosstabs? I'm using v7.03 build 10063.
