Error feedback MUST be meaningful.


Even when people are aware that an error in a form has occurred, they may not know how to correct it. Whenever it is possible, error messages should provide appropriate suggestions for correction of an input error such as: an example format for a date or account number; information on characters that may not be used in a field; or notification that data is not within the expected range. This will allow people to recover from mistakes more easily while filling out a form.

How to Fix

Fix this issue by providing the required data format in the error message, for example: "Enter expiration date in format MM/YYYY"
