Remove errors for questions that no longer apply

What to change

Require validation to follow the current visible route through the form, including when a visitor changes an earlier answer after a failed submission.

A worked example

Illustrative example

Selecting a return call requires a number. After changing to email contact, the old missing-number error disappears and the email requirement becomes the relevant check.

How to check the result

Accept when errors always describe the current answers and reachable questions, including after several changes of direction.

A mistake to avoid

Simply hiding the red message can leave the underlying form blocked by a rule the visitor cannot see.

Your action checklist

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.

Decisions to recordChoose an option that reveals a required field and leave it blank. Submit to produce an error, then switch to an option where that question is irrelevant.Inspect the summary, inline messages and final submission. Ask the supplier to demonstrate that the hidden question no longer blocks the chosen route.Switch back again to the original option. Check whether its current requirement and any retained value are presented clearly without reviving an unexplained stale message.
