 | This is a documentation subpage for Template:Formatting error. It may contain usage information, categories and other content that is not part of the original template page. |
Outputs an error message in red into the page and adds the page to Category:Pages with incorrect formatting templates use. An anchor (FormattingError) is inserted at the start of the error message, so you can find any errors on a page easily by adding #FormattingError at the end of the URL (e.g. Template:val/test#FormattingError). Used in complex templates that check their arguments for validity, so incorrect use can be spotted while editing a page or afterwards.
