Aphthous ulcer
Hi, your edit inserted a named reference tag, but no actual citation details of what was being referenced; hence red-coloured item 22 in the reference list of:
 * "Cite error: Invalid tag; no text was provided for refs named DRWELL ")

See WP:FOOTNOTES, but in essence place some details between an opening and closeing ref tag (named closing tags only used to indicate a duplicate use of an existing defined citation).

Hence perhaps: Aphthous article name, source, year, url web address

Without a suitable WP:Reliable sources, information is likely to get removed as not meeting WP:Verify. Also see WP:MEDRS for further information on what makes a good source for medical topics.

If you need any help in marking up reference details, just ask me or at the article's talk page :-) David Ruben Talk 10:00, 21 November 2008 (UTC)
