I have a form with two date fields, "certDate" and "expireDate" (both set to mm/dd/yyyy format). Once a date is entered into the first field, "certDate", the date entered into the second field, "expireDate", can't be more than two years later than the first date. It can be less than two years later than the first date, but can't be earlier than the first date. How should "expireDate" be scripted?

Absolutely nothing happens. The validation code might as well not exist. The user can enter anything into the second field. Your suggested code change has no effect whatsoever.

In the second script remove .value from:

if (days.value > 730) {

You can write a custom validation script to do it. You need to convert the string values of the fields to Date objects and then you'll be able to manipulate those objects and check they don't pass a certain threshold. If they do, you can reject the user's value by setting event.rc as false in your code.
