# `type.unknown_variant_field`

Variant has no such field.

Area 2, [Values and types](../topics/values-and-types.md); not declinable; the next step is usually the agent's.

```jadpo
type DeclineReason = Text {
    max_length: 200
}

type PaymentOutcome = Enum {
    declined: {
        reason: DeclineReason
    }
}

function declined_payment(reason: DeclineReason) -> PaymentOutcome {
    return PaymentOutcome.declined {
        reason: reason
        note: reason
    }
}
```

```text

  reason: `PaymentOutcome.declined`'s fields are `reason`.
  next: Remove `note`, or declare it on `PaymentOutcome.declined` (agent)
