I am using magento version. I have Customised Reward Points Extension.

In that i need to update Checkout cart Grand Total price while updating the cart based on Discount/Offer applied.(Attached Screenshot).

I used observer sales_quote_save_after with following code:

$quote = Mage::getModel('checkout/session')->getQuote(); $quote->collectTotals()->save();

But site is not working after this code inserted.

How to solve it.

  • Hi! "But site is not working after this code inserted." - it means that you get error? Can you share error text?
