data not reaching overridden ToString() method
<p>I have an overridden ToString() method that I want to output formatted data. This data consisted of 11 different items.  I can get all but one item to display properly but that one item just shows up as 0.  Somehow, it is not reaching the ToString() method.  I debugged the program and followed the data line by line and it disappears at the point right before going to the ToString() method and I have no idea why.  Here is my code.  I'm only posting the code I think is involved with passing the data.  If I am wrong and all of the code is needed, let me know.</p>

<pre><code>private void btnPaymentButton_Click(object sender, EventArgs e)
    {            
        amountPaid = double.Parse(this.txtAmountPaid.Text);

        orderPaymentObject = new Payment(orderObject.TotalAmountDue, amountPaid);            

        this.txtNumberOfPizzaOrdered.Clear();
        this.txtNumberOfCokesOrdered.Clear();
        this.txtAmountDue.Clear();
        this.txtAmountPaid.Clear();

        this.lblYourOrder.Visible = true;
        this.rtxtYourOrder.Visible = true;

        this.rtxtYourOrder.Text =  orderObject.ToString();               
    }     

.......

public class Payment
{
    PizzaOrder orderObject;
    double amountPaid = 0.0,
            totalAmountDue = 0.0;        

    public Payment()
    {
    }

    public Payment(double amountDue, double payment)
    {  
        orderObject = new PizzaOrder();
        amountPaid = payment;
        totalAmountDue = amountDue;
        orderObject.GetChangeDue(totalAmountDue, amountPaid);
        //orderObject.ToString();            
    }

    public Payment(double payment)
    {
        amountPaid = payment;
    }

    public double AmountPaid
    {
        get
        {
            return this.amountPaid;
        }
    }
}

......

public override string ToString()
    {
        Payment paymentOrder = new Payment();

        return string.Format(" {0} Pizzas @ {1:C}: {2,8:C}\n" +
            " {3} Cokes @ {4:C}:  {5,8:C}\n" +
            "       Order Amount: {6,8:C}\n" +
            "             Sales Tax: {7,9:C}\n" +
            "         Amount Due: {8,8:C}\n" +
            "         Amount Paid: {9,9:C}\n\n" +
            "              Change Due: {10,9:C}", NumberOfPizzas, 
            PIZZA_PRICE, totalCostOfPizza, NumberOfCokes, COKE_PRICE,
            totalCostOfCoke, FoodAndDrinkTotal, TotalSalesTax, 
            TotalAmountDue, paymentOrder.AmountPaid, GetChangeDue(totalAmountDue,amountPaid));
    }        
</code></pre>

<p>The value that is not being passed is the amountPaid (second from last).  I've tried passing the amountPaid varible in the OrderFrom class by instantiating an OrderForm object both inside and outside of the ToString() method.  I've tried passing the amountPaid variable in the Payment class by instantiating a Payment object both inside and outside of the ToString method.  I've tried calling inputting the amountPaid variable in the toString method as a variable and as a property. To be honest I've grasped at so many straws that I am now completely confused and have no idea what to do.</p>
