I am developing a VB Userform which includes a start date (Date referral received) and end date (Case resolved date). I am wanting to develop a message box that illustrates a message when the user has put in an end date which is earlier than the start date e.g. "The Case Resolved Date cannot be before the Date Referral Received Date - please review the Case Resolved Date.

Can someone please assist me with some suggested code.

thanks
