| ## fi-0082: Invalid selector value {:#fi-0082} | 
 |  | 
 | This error occurs when you use an invalid value for an [@selector][82-selector]. | 
 | Most commonly, this is due to a typo. A selector must either be a standalone | 
 | method name, or a fully qualified method name. | 
 |  | 
 | {% 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-0082.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %} | 
 | ``` | 
 |  | 
 | To fix this, update the selector to either be a valid standalone, or fully | 
 | qualified method name: | 
 |  | 
 | {% 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-0082.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %} |
