PHP question ... how do I make this work?
 

How can i make this code work to select my recruitment tab when I am on the content.php page viewing specific article/section (r=179-Recruitment)?

Code:
$tabselected = '';
$tablinks = '';
if (THIS_SCRIPT == 'content.php?r=179-Recruitment')
{
$vbulletin->options['selectednavtab']='Recruitment';
$tabselected = ' class="selected"';
}
$template_hook['navtab_start'] .= 'RECRUITMENT'.$tablinks.'' ;
