i want to do simple things in report, but ...
i have db, table, rows, columns, data etc , for example let`s take column_A and column_B
i want to have 3 fields,
x = max(column_A) and y = min(column_B) and z = x - y
in short i want subtract result ( ( max(column_A) - min(column_B) ) and put in another field (number 3). I hope you all understand my wishes

As far i known with calculated fields it cannot be done, because of syntax ? Because can`t subtract calculatedfield1-calculatedfield2 , and calculatedfield even can not show max and min values
Best Regards.
Thanks in advance.
