In this situation an error handling passage is needed, users will perriodically make input errors. Design considerations are oft focused on the wrong issues, to much time is washed-out on formulating the desired error message and where it must be displayed in the process.

Frequently system programmers will design a system that provides instructions built into the application, therefore providing the correct input format. So the users can understand exactly how they should enter the data. However, even this does not always help, users still make input errors, and developers remonstrate about their stupid users.
