How do you add days to a date field using JavaScript in LiveCycle Designer ES2? I have a field named DTFBeg that is a user-input field. I'd like to take this value, add 7 days to it, and display the new value in the field called DTFThru. Both the fields are on the Master Page of a flowable form. I've tried so many different JavaScript options from different samples I've found online, but nothing I've tried pulls a value anywhere close to what I'm looking for.
Thanks in advance to anyone who can help!
