Cite error: Invalid parameter in <references> tag
Usage
Use this template to create a reference list in an article.
If used with no parameters, it will simply produce a reference list in a small font.
Multiple columns
Using {{reflist|2}} will create a two-column reference list, and {{reflist|3}} will create a three-column list.
Using {{reflist|colwidth=30em}} will allow the browser to automatically choose the number of columns based on the width of the web browser. Choose a column width that's appropriate for the average width of the references on the page.
