# `type.unknown_value`

Name is not defined in this scope.

Area 3, [Logic](../topics/logic.md); not declinable; the next step is usually the agent's.

```jadpo
type Name = Text {}

function echo(name: Name) -> Name {
    return nmae
}
```

```text
error: `nmae` isn't defined in this scope
 --> main.jadpo:4:12
  |
4 |     return nmae
  |            ^^^^ not defined
  reason: Jadpo could not find this name. Did you mean `name`?
  next: Use `name` instead of `nmae` (agent)
