I am working on this web developer page for my vb class and i can't seem to get my values to display. Can someone tell me why my values are not displaying? Here is the code that i have so far:

'Programmer:    Cassie Sanford
'Date:          October 12, 2008
'Description:   A website to calculate the extended price for books sold,
'               a discount, and the discounted amount. Calculates and displays
'               the total discounts. Uses validator controls for input validation.


Partial Class _Default

    Const DISCOUNT_RATE_Decimal As Decimal = 0.15D


    Protected Sub submitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitButton.Click
        Dim quantityInteger As Integer
        Dim priceDecimal, extendedPriceDecimal As Decimal
        Dim discountDecimal, discountedPriceDecimal As Decimal

        With Me
            .errorMessageLabel.Text = String.Empty
            Try
                'Convert input values to numeric variables.
                quantityInteger = Integer.Parse(.quantityTextBox.Text)
                priceDecimal = Decimal.Parse(.priceTextBox.Text)

                'Calculate values for sale.
                extendedPriceDecimal = quantityInteger * priceDecimal
                discountDecimal = extendedPriceDecimal * DISCOUNT_RATE_Decimal
                discountedPriceDecimal = extendedPriceDecimal - discountDecimal

                'Add to the discount total.
                discountTotalDecimal += discountDecimal
                'Save the discount total in a hidden field.
                .discountTotalHiddenField.Value = discountTotalDecimal.ToString()

                'Format and display the answers.
                .extendedPriceTextBox.Text = extendedPriceDecimal.ToString("C")
                .discountTextBox.Text = discountDecimal.ToString("N")

I use a 12X3 table in the default.aspx application and a 4X2 in the contacts section....help is urgently needed!!!

i followed the directions but it keeps saying that The value '' of the MaximumValue property of 'priceRangeValidator' cannot be converted to type 'Currency'. What can i do to solve ths problem??????

In the problem i have to declare price and quantityRequiredFieldvalidators, as well as their range validators. They didn't give any ranges for the price, and im stuck on what to do
