Help on Correcting Code - Userage Permission

[Exitilus]

O.o ...

It must hate me :| *twitch*

This is the exact code i'm trying to use

PHP Code:

$current['day'] = date('d');
if ((($current['year'] - $vbulletin->GPC['year']) <  $vbulletin->options['minjoinage']) OR ((($current['year'] - $vbulletin->GPC['year']) == $vbulletin->options['minjoinage']) AND (($vbulletin->GPC['month'] < $current['month']) OR ($vbulletin->GPC['month'] == $current['month'] AND $current['day'] < $vbulletin->GPC['day']))))
{ 
    eval(standard_error(fetch_error('underage_registration_denied', $vbulletin->options['minjoinage'])));  
}
