Editing Template:Refn/doc (section)

===Errors===
If the reference or note content is missing, then Cite error: Invalid &lt;ref&gt; tag; refs with no name must have content. will be displayed.

If the note content contains an equals sign (<code>=</code>), the equals sign will be interpreted as setting off a named parameter and cause an error. This can be worked around by [[Help:Template#Usage hints and workarounds|using a numbered parameter]], for example:

{{markup
|1=<nowiki>{{refn|1+1=2}}</nowiki>
|2=<span class="error mw-ext-cite-error">Cite error: There are &lt;ref&gt; tags on this page without content in them (see the [[Help:Cite errors/Cite error ref no input|help page]]).</span>
|3=<nowiki>{{refn|1= 1+1=2}}</nowiki>
|4={{refn|1= 1+1=2}}

{{reflist}}
}}
