Chapter 13 C# Version getting error with class
I am at the end of chapter 13 in the C# version of this book. When ever i try to run my page it tells me that Wrox.Commerce.ShoppingCart does not contain a definition for SubTotal, and MemberDiscount. I looked through the book and it never has me create a method for either of these items in my Shopping.cs class, but it asks for them as parameters in the check out. Is anyone else having this problem? I am stumped...
