Fix coupon code issue (Display amount in cart)

[rojones31]

Hello,

I have an urgent issue I'm trying to solve. 

Another issue i'm having is that, I created a coupon code for my clients to use, however once the customer inputs the code into the cart during checkout the code works, because the amount of the code value is not be displayed in the cart during checkout, so the client can not see how much the code was applied.  How can I fix this issue to display the coupon code amount in the cart correctly?  Also, the coupon amount also does not appear in the invoice as well.

Using Joomla! 3.4.0 Stable & VirtueMart 3.0.6.2

Please help!
