I USED FAST REPORT 3.0, AND FOUND QUESTIONS AS BELLOW.
AGGREGATES MATHODS ARE DETACHED FROM BUILT-IN FUNCTIONS ( AS THAT OF FR 2.X). IF YOU WANNA DO SOME FUNCTION LIKE:
MYFUNCTION([SUM(DS.FIELD, BAND1)])
MYFUNCTION MEANS ANY FUNCTION DECLARED IN FR.
FR 3.0'S COMPLIER WILL NOT RECOGNIZE THE FUNCTION SUM(), AND WILL RAISE AN EXCEPTION: 'UNDECLARED IDENTIFIED SUM.....'; 'CAUSE SUM() IS NOT DECLARED AS A FUNCTION. BUT I NEED TO PROCESS THE AGGREGATES RESULT.
HOW CAN I RESOLVE THIS PROBLEM?
