Category:Pages using duplicate arguments in template calls

If your page is in this category, it means you have some template where you assign an argument more than once. This is usually the result of poorly-checked copying and pasting; for instance,

 {{TeamInfobox
...
|altgh1=goalhorn.mp3
|altgh1_title=A Goalhorn
|altgh2=goalhorn2.mp3
|althg1_title=Another Goalhorn
...
}}

specifies altgh1_title twice. The second should be changed to altgh2_title.
