Hey again, Savvy psychologist. In this edit, regarding the biography.com source, you used a ref attribute without using the whole source. A ref attribute without the whole source is useless. Here, I'll explain: Attributes are for multiple citations of the same reference or footnote. This is done so that you don't have to use the same reference repeatedly in whole. Whether you are using citation templates or not, you can use ref attributes by using <ref name=name>details of the citation</ref>. Thereafter, the same footnote may be used multiple times by adding <ref name=name/>. If the name contains an embedded blank space, you must either add straight quotation marks (<ref name="name more"/>) or replace the unacceptable blank space with an acceptable symbol such as an underscore or a hyphen (e.g., <ref name=name_more/> or <ref name=name-more/>), thus eliminating the need for quotation marks. The name is case-sensitive, but quoted names match names without quotes; USGS is matched by "USGS" but not by usgs.
That's why I removed your ref attribute -- it was without all the source information. Thank you for sourcing the other bit, though. You properly sourced it, and it's an okay reference. Flyer22 (talk) 18:46, 9 September 2011 (UTC)[reply]
