## fi-0053: Cannot refer to member {:#fi-0053}

This error occurs when you refer to a member that's not a `bits` or `enum` entry.

{% 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-0053-a.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```

```fidl
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0053-b.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```

To fix this error, either change to a named type:

{% 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-0053-a.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```

or extract the member's type:

```fidl
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0053-b.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```
