Hikashop wont go to final checkout page in payment system - hikashop USAepay. Also, get same error message in Bank Draft checkout.

-- Error message:

Hi,

Firstly, can you download the last version of Hikashop through our website, install it, and tell me if it solved your problem ?

Thanks .

Ok, I just installed latest version HikaShop Essentials. I still get the same error message. Please advise.

In the checkout.php file there was an error on 1456. The word amount was mispelled. However, the cart is still not processing credit card and going to final checkout page. Please help, my client is getting impatient. Thanks

Ok, so if you replace :

$tax->tax_amout;

$tax->tax_amount;

I fixed the error message with the word tax in line 1456. However, the credit card still does not process. There is no message when I click the next button. It just stays on the page - no errors, no messages , no redirects....
