Editing Template:See also/doc (section)

==Errors==
If no page names are supplied, the template outputs the following message with the (help) wikilink pointing to the "Errors" section of this page: 
*{{See also|category=no}}

If you see this error message, it is for one of three reasons:
# No parameters were specified (the template code was <code><nowiki>{{See also}}</nowiki></code> with no pipe character nor page to link to). Please use <code><nowiki>{{See also|</nowiki>''page''<nowiki>}}</nowiki></code> instead.
# Some parameters were specified, but no page names were included. For example, the template text <code><nowiki>{{See also|selfref=yes}}</nowiki></code> will produce this error. Please use (for example) <code><nowiki>{{See also|</nowiki>''page''<nowiki>|selfref=yes}}</nowiki></code> instead.
# A page name was specified, but it contains an equals sign ("="). The equals sign has a special meaning in template code, and because of this it cannot be used in template parameters that do not specify a parameter name. For example, the template code <code><nowiki>{{See also|1+1=2|2+2=4}}</nowiki></code> will produce this error. To work around this, you can specify the parameter name explicitly by using <code>1=</code>, <code>2</code>, etc., before the page name, like this: <code><nowiki>{{See also|1=1+1=2|2=2+2=4}}</nowiki></code>.

If you see this error message and are unsure of what to do, please post a message on [[WP:HD|the help desk (WP:HD)]], and someone should be able to help you.
