==Issues and resolution==

All references defined in the reference list must be invoked in theprior content. Unused references must be removed or commented out, or stripped of their {{tag|ref}} tags and moved to another section, such as "Further reading".

----

Placing a template that creates {{tag|ref|o}} tags inside of {{tag|ref|o}} tags may also cause this. Known instances:

Including more than one nested reference in {{ldr}} will cause a Cite error.

* {{tl|Singlechart}}

----

* {{tl|SinglechartSingle chart}}

* {{tl|Certification Table Entry}}

==Examples==

{{Help:Cite errors/lang}}

{{xt|Ex. 1) There are three references defined in the list, but none are invoked in the content. Note the spurious error for the first reference named ''ipsum'':}}

{{pre2pre|<nowiki>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.

{{xt|If only one reference is defined but not invoked, then only the spurious error is shown:}}

{{xt|Ex. 2) A {{tag|ref|attribs=name="..."|single}} tag is invoked ''after'' the reference list:}}

{{pre2pre|<nowiki>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Line 65 ⟶ 82:

}}

<ref name=ipsum />

{{xt|Ex. 3) Not so obvious case. If you mistakenly nest an {{tl|sfn}} type template inside {{tag|ref}} as in the second footnote below, an error message will show:}}

{{pre|<nowiki>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.<ref>{{harvp|foo|1999|p=123}}</ref> Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.<ref>{{sfnp|Foo|1999|p=123}}</ref>

==References==
