Pagify Plugin

[xxdex]

i'm create a new special field with I18N Custom Fields
name= pagination
title= enable / disable pagination
type = dropdown box --> 1. no 2. yes
default = no

and in template i was give this lines:
(in head)
<?php
$paginationone = return_custom_field('pagination');

if ($paginationone == 'yes') {
$paginationend='_pagify';
} else if ($paginationone == 'no') {
$paginationend=''";
}
?>

<meta name="paginationbox" content="<?php echo $paginationend ?>" />

ok.. in front template is working (it's giving a filed like
<name="paginationbox" content="_pagify" />
if dropdown in front-end page is checked "yes"

and
<name="paginationbox" content="" />
if dropdown in front-end page is checked "no"

how to enable to this name pagify because it's not working in tag <name="paginationbox" >
how to change a default
<meta name="keywords"
for a simple
<name="paginationbox"
..

or if someone have a better idea.. please help ... and answer
