# `type.duplicate_variant`

Enum variant is declared twice.

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

```jadpo
type TicketStatus = Enum {
    open
    closed
    open
}
```

```text
error: `TicketStatus.open` is declared twice
 --> main.jadpo:4:5
  |
2 |     open
  |     ---- first declared here
4 |     open
  |     ^^^^ declared again
  reason: Each variant of an enum has its own name, so a value and a `match` arm name exactly one.
  next: Remove one `open`, or rename it (agent)
