Editing Template:See also/doc (section)

== Errors ==

If no page names are supplied, the template will output the following message:
* {{see also|category=no}}

If you see this error message, it is for one of four reasons:
# No parameters were specified (the template code was <code><nowiki>{{see also}}</nowiki></code>). 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>.
# You tried to access [[Module:See also]] directly by using <code><nowiki>{{#invoke:see also|seealso|</nowiki>''text''<nowiki>}}</nowiki></code>. Use of #invoke in this way has been disabled for performance reasons. Please use <code><nowiki>{{see also|</nowiki>''text''<nowiki>}}</nowiki></code> instead.
