That seems complicated just to say nulls last. I know how to do it in sql, but just not in Crystal.
It is currently grouped by age. There is a formula field that says take todays date and subtract their birthdate to calculate their age. Then it is grouped by this field so that the group footer counts how many people are in each grouping eg. 5 in '34', 8 in '35, 20 in '40'. But they are not required to fill in the date of birth and sometime my clients need to know which people don't have this field filled in, so the nulls need to be on the report, but rather than them taking up the first 2 pages, I'd rather have them at the end of the report. Is this possible? Does that make more sense?
