Hi Nate,
I think you should remove the global binding and use a calculate event in the second date field, Something like this JavaScript
if (!DateField1.isNull) {
var date = util.scand("yyyy-mm-dd", DateField1.rawValue);
if (date != null) {
date.setMonth(date.getMonth() + 9);
util.printd("yyyy-mm-dd", date);
}
}
You should just need to change the name of the first date field from the DateField1 name I have used in the above sample.
