View source for Template:CheckPages1

<noinclude>
The template takes the following 3 parameters:
<div class="definition-inline">
; |1= : optional previous error message(s)
; |2= : First page
; |3= : Last page
</div>
It checks whether the parameter “First page” is larger than the parameter “Last page”. If yes then an error message is returned. If the Error message (first parameter) already contains some text then the separator “;;” and the new message is appended. If there is no error parameter 1 is returned.

Usage:
 <nowiki>{{</nowiki>{{PAGENAME}}|1=previous error|2=16|3=13}}
 {{ {{PAGENAME}}|1=previous error|2=16|3=13}}
 
 <nowiki>{{</nowiki>{{PAGENAME}}|1=previous error|2=E4|3=E3}}
 {{ {{PAGENAME}}|1=previous error|2=E4|3=E3}}
 
 <nowiki>{{</nowiki>{{PAGENAME}}|1=previous error|2=12|3=13}}
 {{ {{PAGENAME}}|1=previous error|2=12|3=13}}

Returns:
* error message or none
