Call to a member function on a non-object

Question

I keep getting the following error :

PHP Fatal error: Call to a member function setCollectShippingRates() on a non-object in /chroot/home/Client/Client.com/html/app/code/local/Company/Checkout/controllers/OnepageController.php on line 12

I don't know if its something to do with $result or setCollectShippingRates() ? Maybe Varien Data somehow? Thanks for the help.

app/code/local/Company/Checkout/controllers/OnepageController.php

require_once'app/code/local/Mage/Checkout/controllers/OnepageController.php';

class Company_Checkout_OnepageController extends Mage_Checkout_OnepageController
{
    public function couponAction()
    {
        $this->loadLayout('checkout_onepage_review');
        $this->couponCode = (string) $this->getRequest()->getParam('coupon_code');

        Mage::getSingleton('checkout/cart')->getQuote()->getShippingAdress()->setCollectShippingRates(true);
        Mage::getSingleton('checkout/cart')->getQuote()->setCouponCode(strlen($this->couponCode) ? $this->couponCode : '')-> collectTotals()->save();

        $result['goto_Section'] = 'review';
        $result['update_section'] = array('name' => 'review', 'html' => $this->_getReviewHtml());

        $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
    }
}

Try like this:

require_once 'Mage/Checkout/controllers/OnepageController.php';

class Company_Checkout_OnepageController extends Mage_Checkout_OnepageController {
    public function couponAction() {
        $this->loadLayout('checkout_onepage_review');
        $this->couponCode = (string) $this->getRequest()->getParam('coupon_code');

        Mage::getSingleton('checkout/cart')->getQuote()->getShippingAdress()->setCollectShippingRates(true);
        Mage::getSingleton('checkout/cart')->getQuote()->setCouponCode(strlen($this->couponCode) ? $this->couponCode : '')-> collectTotals()->save();

        $result['goto_Section'] = 'review';
        $result['update_section'] = array('name' => 'review', 'html' => $this->_getReviewHtml());

        $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
    }
}
