What happens if a user inputs data incorrectly in a screen step?

When a user inputs data incorrectly in a screen step, the expected behavior is that the user will be prompted to correct the input. This is crucial for maintaining data integrity and ensuring the accuracy of the information being processed. By providing immediate feedback, users have the opportunity to review their entries and make necessary adjustments before proceeding further. This approach not only minimizes the risk of errors in data handling but also enhances the overall user experience by guiding users to provide valid inputs.

The other options do not align with the standard functionality in systems designed for data input. Allowing the guide to proceed with incorrect data could lead to significant issues down the line, such as data corruption or loss of valuable insights. Logging the error is a useful feature for tracking but does not address the immediate need for correction. Likewise, while it is important to ensure accurate inputs, preventing the user from continuing could lead to frustration if not accompanied by guidance to correct the information. Therefore, prompting for corrections is a balanced approach that supports both data quality and user engagement.
