I have upgraded from 1.7 to version 1.9.1. I have made many changes but nothing is working.
Luckly i manage to fix login page and update cart with few code change in id etc.
Anyone have any idea. i am realy stuck. 
Wht changes i have made regarding placing an order so far
i have added this at the bottom of info.html
review = new Review('<?php echo $this->getUrl('checkout/onepage/saveOrder', array('form_key' => Mage::getSingleton('core/session')->getFormKey())) ?>', '<?php echo $this->getUrl('checkout/onepage/success') ?>', $('checkout-agreements'));
I also added this value in payment.phtml public_html/app/design/frontend/base/default/template/checkout/onepage
<fieldset id="checkout-payment-method-load">
<?php echo $this->getChildHtml('methods') ?>
</fieldset>
but no luck. the page does not go anywhere at all. any idea!!!!!!!!!!!!!!!!!!!!!!!!!!
