Select  Partno		;
>	, Sum (RealCost)	As RealCost		;
>	, Sum (PostedCost) 	As PostedCost	;
>	, Sum (RealCost - PostedCost)	As Variance		;
>	, Sum (1)		As Count		;
>	, Sum (NItems)	As NItems		;
>	;
>	from c_Source	                                          ;								;
>	group By 1	;	;
>	into Cursor c_Browse Readwrite

>I'd like to be able to reference the RealCost field in the result in the HAVING phrase ... HAVING RealCost # 0 ... but I get an error message because of the name conflict with the field RealCost in the source cursor.
