I have a quandry, I need one cell for users to put in a date. The date can only be between todays date and the 31/12/12...I have set this up in Data Validation, so all ok, however. I now also need a warning message to pop if the date they enter is not a Sunday date. It should still let them continue though if they want to, or give them the opportunity to retry. Does anyone know how I could incorporate them both please
