Best Practice 3.4 – Provide error identification (Baseline level)

If a user makes a mistake, use text to show where and what has done wrong, and provide hint for how to fix it.

Before Rectification In this example, an error has been identified but without specific error message prompted.

After Rectification More specific error message should be given so that users know exactly what is wrong.
