Hi radzmar, I want to apply a similar function to a message box. When the user clicks on 'submit' to attach the form to an email I want to ask them if they're sure the form is complete. This is OK if they choose yes, the form attaches to the email, but it also attaches to an email if 'no' is chosen. What do I need to include to cancel the email and return to the form if they choose no. Thanks.
