## fi-0063: Expected value but got type {:#fi-0063}

The right-hand side of a `const` declaration must resolve to a constant value,
not a type:

{% include "docs/reference/fidl/language/error-catalog/label/_bad.md" %}

```fidl
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0063.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```

Ensure that the right-hand side is a value:

{% include "docs/reference/fidl/language/error-catalog/label/_good.md" %}

```fidl
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0063.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```
