Category:Pages using duplicate arguments in template calls

This category contains pages with template calls that pass the same argument more than once, such as {{foo|bar=1|bar=2}} and {{foo|bar|1=baz}}. Open any of these articles in an editing window, click the Show preview button, and the software will highlight which parameter and which template needs attention. Search for and correct the parameter (e.g. by removing duplicates). Preview the page again and save the page IF the software message is no longer present. Otherwise there may be more than one duplicate parameter that needs correcting.
