Agnes,

I try to avoid calculated fields in reports as much as I can.

Instead I add them to the cursor

Advantages
- Easier
- The expression is always available. You can eg display the total in the group header, or a % of total in the detail

I would do something like this

	create cursor SchnapsTmp ;
	(	a	c(1), ;
		b	c(1),; 
		c	c(1) ;
	)
	insert into SchnapsTmp values ('', 'x', 'y')
	insert into SchnapsTmp values ('', 'x', 'y')
	insert into SchnapsTmp values ('a', 'x', 'y')
	insert into SchnapsTmp values ('b', 'x', 'y')
	insert into SchnapsTmp values ('c', 'x', 'y')
	
	select * ;
		from SchnapsTmp, ;
			( select count(*) as NumberA from SchnapsTmp where ( a <> '') ) XX;
		into cursor Schnaps
		
	use in SchnapsTmp 
	
	&& report cursor = Schnaps
