I need to add a constraint to a dateTime field that only allows a date that is at least 15 days after the submittal date. I am trying to use this calculation:
.>=(today() + (1000 * 60 * 60 * 24 * 15))
but get a 'Please enter a valid value' message now when trying to enter ANY date.
Can anyway determine what I'm doing wrong? I modified a formula in the Constraints section here:

Thanks!
