# `type.duplicate_variant_field`

Variant field is given twice.

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
        reason: reason
    }
}
```

```text
error: `reason` is given twice

   |
13 |         reason: reason
   |         ------ first given here
14 |         reason: reason
   |         ^^^^^^ given again
  reason: Each field of `PaymentOutcome.declined` is given once, so there is never a question of which value counts.
  next: Remove one `reason` (agent)
