Need help auto-populating dates.

So you want to enter the first field, and have the rest of them fill in automatically?

If so, it's just a matter of adding 1 year, or 1 day, to each one.

The basic code would be something like this (as the custom validation script of the first field):

if (event.value) {
	var d = util.scand("mm/dd/yyyy", event.value);
	d.setFullYear(d.getFullYear()+1);
	this.getField("Expiration1").value = util.printd("mm/dd/yyyy", d);
	d.setDate(d.getDate()+1);
	this.getField("Effective2").value = util.printd("mm/dd/yyyy", d);
	d.setFullYear(d.getFullYear()+1);
	this.getField("Expiration2").value = util.printd("mm/dd/yyyy", d);
	// etc.	
}
