Hi !

What would be the best way to calculate the differense between to columns
for each record in the detail band ?

Column 1 Column 2 Differense
--------------------------------------
10 8 2
8 10 -2


Thanks

    I would use a variable and use the OnCalc event:

    Value := Query['Column1'] - Query['Column2'];
