C# with SQL Database Data in PayPal Smart Button Order List

Question

I am working on a C# Web Forms project where I have created a Class to handle various functions of a shopping cart that I am integrating with the new PayPal Smart Buttons using the PayPalCheckoutSdk. Inside of my ShoppingCartActions Class I am running a function that displays the total price of an item based on quantity; everything works fine with this code:

public decimal GetTotal()
        {
            ShoppingCartId = GetCartId();
            // Multiply product price by quantity of that product to get        
            // the current price for each of those products in the cart.  
            // Sum all product price totals to get the cart total.   
            decimal? total = decimal.Zero;
            total = (decimal?)(from cartItems in _db.ShoppingCartItems
                               where cartItems.CartId == ShoppingCartId
                               select (int?)cartItems.Quantity *
                               cartItems.Product.UnitPrice).Sum();
            return total ?? decimal.Zero;
        }

I am able to display the value on my Cart Page with the following code:

public static string price;
protected void Page_Load(object sender, EventArgs e)
{
    using (ShoppingCartActions usersShoppingCart = new ShoppingCartActions())
    {
        cartTotal = usersShoppingCart.GetTotal();
        price = String.Format("{0:c}", cartTotal);
        Lbl01.Text = price;
    }
}

Here is where my issue comes in: I am wanting to use this value in an Order Request for Paypal but when I try it will not display a value! Below is OrderRequest:

public OrderRequest orderRequest = new OrderRequest()
        {
            CheckoutPaymentIntent = "CAPTURE",

            },
            PurchaseUnits = new List<PurchaseUnitRequest>
                {

                            AmountBreakdown = new AmountBreakdown
                            {

                                {

                                    Value = "100.00"<<<<<<<<< I tried here as well but nothing displays!
                                },
                                Tax = new Money

                        ShippingDetail = new ShippingDetail
                        {
                            Name = new Name
                            {

                                AddressLine1 = "",
                                AdminArea2 = "",
                                AdminArea1 = "",
                                PostalCode = "",

                            }
                        }
                    }
                }
        };

How can I set the string value to be read inside of the Order Request? Any help is GREATLY appreciated!
