Editing Module:Format link/doc (section)

== Errors ==

If <var>_formatLink</var> is used and neither a <var>link</var> nor a <var>target</var> argument is provided, then the module will produce an error message instead of its usual output, as it ''cannot'' then produce valid output.

You can solve this error by providing appropriate parameters to <var>_formatLink</var>, or you may want to ensure that a more descriptive error is provided by a downstream template or module when it would otherwise call <var>_formatLink</var> with inadequate arguments.
