This page will help you to fix the cite error message:

A list-defined reference with the name "$1" has been invoked, but is not defined in the <references> tag (see the help page).

• If you have read this help page and find something missing or confusing, please discuss it at the main talk page.
• Please reference this page and the page where you have the problem so we can understand your issues.
• For basic information on the footnotes system, see Referencing for beginners; for advanced help, see Footnotes.

References may be defined within the reference list:

{{reflist|refs=
<ref name=rename1>refcontent1</ref>
}}

Note: It is possible to get this error message when nesting footnotes in list-defined references, unfortunately the only fix in this situation is to not use list-defined references for entries that are nested.

• A list-defined reference has no content between the <ref>...</ref> tags.
• This error message does not show if {{ reflist}} is used.
• Footnotes are nested inside list-defined references. This is a known bug, for now just do not use list-defined references.

The reference named foo is defined but has no content:

<ref name="foo" />

<references>
<ref name="foo"></ref>
</references>
