ssp setting a parameter from a column in array

I need to set a variable based on the the value of column in a ssp script , but for some reason it is not returning the value.

$outOfOffice = '';

$columns[] =  array( 'db' => 'OUT_OF_OFFICE', 'dt' => 'out_of_office',
    'formatter' => function($d, $row) use ($outOfOffice) {
        $outOfOffice = trim($row['OUT_OF_OFFICE']);
        return trim($row['OUT_OF_OFFICE']);
      }
    );

if($outOfOffice == 'Vacation Day'){

    $columns[] = array( 'db' => 'TOTAL_HOURS_SECONDS', 'dt' => 'total_vacation_hours',
        'formatter' => function($d, $row){
        
        $totalVacationhours   = floor($row['TOTAL_HOURS_SECONDS'] / 3600);
        return   $totalVacationhours;

        }
     );
    
}else if ($outOfOffice == 'Paid Leave Vacation'){
    
    $columns[] = array( 'db' => 'TOTAL_HOURS_SECONDS', 'dt' => 'total_paid_leave_vacation_hours',
        'formatter' => function($d, $row){
        
        $totalPaidLeaveVacationHours   = floor($row['TOTAL_HOURS_SECONDS'] / 3600);
        return   $totalPaidLeaveVacationHours;
        }
    );
}
