Cecil,

OK, as Gary said, you need to have a constructor in your Biz_Tier class that takes two paramters if you want to instantiate your Biz_Tier class this way. But, I bet what you really want is just to call a method on the Biz_Tier class that returns your TotalPrice, rather than pass those two parms into the constructor of the class. So, your code would be something like this:

        private void addButton_Click(object sender, EventArgs e)
        {
            //Instantiate a business tier object.
            Biz_Tier aOrder = new Biz_Tier();

            //Get the total price
            this.TotalPriceTextBox.Text = aOrder.GetTotalPrice(this.unitPriceTextBox.Text, this.unitsTextBox.Text);
        }

>Well, it is middle tier. I am in a C# class in whcih we were given very little of any guidance and were only told to have a business tier, a very simple one. We obtain the data in the first form from an ACCESS database wherein we display a Price and the number of units and the number of untis times that price to get a total price for clkeanign a home's carpets.
