These errors occur when {{cs1}} and {{cs2}} templates use {{para|format}} or {{para|...-format}} without also providing a corresponding URL for {{para|url}} or {{para|...-url}}, respectively. The {{para|format}} and {{para|...-format}} parameters are used to specify the file format of a web resource, such as [[PDF]], [[Doc (computing)|DOC]], or [[Microsoft Excel file format|XLS]]. In some cases an editor may have intended to use {{para|type}} to specify a kind of document, such as hard cover, paperback, or pamphlet. The {{para|format}} and {{para|...-format}} value is always displayed.

The list of {{para|...-format}} parameters is:
: {{para|archive-format}}, {{para|article-format}}, {{para|chapter-format}}, {{para|conference-format}}, {{para|contribution-format}}, {{para|entry-format}}, {{para|event-format}}, {{para|map-format}}, {{para|section-format}}, {{para|transcript-format}}

(<!-- TBD: Ia this still necessary to be mentioned? -->Citations that relied on the pre-2014<!-- 2014-11-29 -->, somewhat odd use of {{para|url}} and {{para|format}} may need adjustment in regard to {{para|chapter-format}}.)

To resolve this error, remove {{para|format}} or {{para|chapter-format}}; define {{para|url}} or {{para|chapter-url}}; or change {{para|format}} to {{para|type}} (or to {{para|chapter-format}} if {{para|chapter-url}} is used without {{para|url}}.
