Rejected Entry With No Suggested Near-Match From a Known List

3.3.3 — Error Suggestion

Scenario

Setting

A community forum's discussion thread

What’s wrong

Search-style inputs with known valid value lists rejecting entries and not suggesting near matches while they're computable.

Example

<span class="error">Invalid input</span>

Why it matters

People with cognitive disabilities and anyone stalled by vague validation messages.

How to test

Enter a near-miss value in a field with a known valid list (e.g., a misspelled city name): if no near-match suggestion is offered where feasible, it fails.

How to fix

The error message must tell the user how to fix the problem — the expected format, range, or valid options.

<span class="error">Enter a year between 1990 and 2026</span>

Error text should suggest the fix — the expected format or valid range — not just flag that something's wrong.

Outcome

On a community forum's discussion thread, this barrier is gone for people with cognitive disabilities and anyone stalled by vague validation messages — they can complete the task without hitting this wall.

Who is affected

People with cognitive disabilities and anyone stalled by vague validation messages.
