Overview
Script error: No such module "labelled list hatnote". A footnote used multiple times may be defined with a name:
<ref name="foo">content</ref>
To invoke a named footnote:
<ref name="foo" />
References may also be defined within the reference list:
Page Template:Pre/styles.css has no content.
{{reflist|refs=
<ref name=refname1>refcontent1</ref>
<ref name=refname2>refcontent2</ref>
<ref name=refname3>refcontent3</ref>
<ref name=refname4>refcontent4</ref>
}}
List-defined references may be invoked by the standard markup or by use of Template:Tl.
Issues and resolution
All references defined in the reference list must be invoked in prior content. Unused references must be removed or commented out, or stripped of their <ref>...</ref> tags and moved to another section, such as "Further reading".
Including more than one nested reference in Template:Ldr will cause a Cite error.
Misusing a template that was never intended as a citation template and placing it in <ref> tags may cause this issue.
A template that creates <ref> tags; known instances:
- Template:Tl
- Template:Tl and variants
- Template:Tl
A template that includes table markup; known instances:
Examples
