I need to create an attributed calendar (date) field that must be automatically filled when the user fill in the "Effective date of Contract" attribute field and a "terms" field that contains ammounts o months duration (i.e 30, 60, 90 months...)
I haven't found any way to acomplish this, I've tryed with Smart Rules or Workflows, but those features didn't calculate the final value (initial date + terms = final expiration daet) in real time ( when the user is manually fillin in the attributes values).
