This page will help you to fix the error message:

The <ref> tag has too many names (see the help page).

  • If you need help with a particular problem, please discuss it on the article talk page or at the Help desk.
  • 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.

Overview

Further information: Help:Footnotes

A footnote used multiple times may be defined with a name:

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

Any footnote can be assigned to a group:

<ref group="foobar">content</ref>

Or both:

<ref group="foobar" name="foo">content</ref>

Names for footnotes and groups must follow these rules:

  • Names are case-sensitive
  • Names may not be purely numeric
  • Names must be unique—you cannot use the same name to define different groups or footnotes
  • Quotes are optional if the only characters used are letters A–Z, a–z, digits 0–9, and the symbols !$%&()*,-.:;<@[]^_`{|}~
  • The quote marks must be the standard keyboard marks ("); curly or other quotes will be parsed as part of the reference name.
  • Inclusion of any other characters, including spaces, requires that the name be enclosed in double straight quotes (")
  • If a name is quoted when defined, it must also be quoted for additional invocations (i.e. name="something" is not the same as name=something).
  • Quote-enclosed names may not include a less-than sign (<) or a double straight quote symbol (")
  • Please consider keeping names simple and restricted to the standard English alphabet and numerals.
  • (You may optionally provide names even when the name is not required.)

Issues and resolution

A named reference tag has too many names or parameters. A quoteless name such as foo bar will be parsed as two separate names due to the space, thus generating the error. You can only specify two parameters, name and group. You can't, for instance, format a reference with <ref style="color:red;">content</ref>, or give it an id.

Examples

In this example, reference 1 is named foo bar, which is invalid due to the space. In reference 2 foo bar is valid as it is enclosed in quotes and reference 3 is valid as foo_bar uses an underscore.

Bugs

This error is not generated if the name fragment after the space contains (not just begins) any other character than A–Z, a–z, 0–9. When this condition occurs, the link is truncated after the space. In this example, although the name fragment after the space contains a different character, all three references generate the same link:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.<ref name=foo |bar>Reference 1</ref> Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.<ref name=foo !bar>Reference 2</ref> Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
