Hello Brian, I've done something similar previously using a combination of a field binding constraint, an eval and the excellent joda-time API (http://joda-time.sourceforge.net/). If I remember right, you'd need something along the lines of :
import org.joda.time.Duration; import org.joda.time.DateTime; Reference($fromDate : fromDate, eval(new Duration(new DateTime($fromDate), new DateTime()).getMillis() > (2*365*24*60*60*1000))) It might be more readable if you can encapsulate this in a function :-) Dean.
