I'm trying to write an expression for a graphic to sum these fields [retr.mese/importo], [retr.mese/contributi], [retr.mese/inail], [lav.strao/importo],[lav.strao/contributi], [lav.strao/inail] from 06/2012 to 09/2012.
Below an example:
codice azienda
codice filiale
matricola dipendente
anno cedolini
mese cedolini
retr.mese/quantita'
retr.mese/importo
retr.mese/contributi
retr.mese/inail
lav.strao/quantita'
lav.strao/importo
lav.strao/contributi
lav.strao/inail

And then how can I calculate the difference between the sum of the fields [retr.mese/importo], [retr.mese/contributi], [retr.mese/inail], [lav.strao/importo],[lav.strao/contributi], [lav.strao/inail] from 06/2012 to 09/2012 and from 06/2013 to 09/2013?
