As I said, you must select the entire document (via Ctrl-A) before updating the issue date. Do that and all the calculations will update. As for your point D, adding the extra calculations is trivial, but it's far from clear as to what the text is actually supposed to say. And, as for the actual date, since 11/12/2014 is a Thursday, should the 7 & 12 weeks count from the preceding Monday, or from the Next Monday?
