    {
        float cartTotal, taxedvalue;
        cartTotal = (float)usersShoppingCart.GetTotal();
        taxedvalue = 6 / 100 * cartTotal;
        cartTotal += taxedvalue;
        if (cartTotal > 0)
        {
            // Display Total.
            lblTotal.Text = String.Format("{0:c}", cartTotal += taxedvalue);
        }
        else
        {
            LabelTotalText.Text = "";
            lblTotal.Text = "";
            ShoppingCartTitle.InnerText = "Shopping Cart is Empty";
            UpdateBtn.Visible = false;

Did you debug and see? Is the code going to if or else part?

Solution 1

You are performing integer division before the multiply, so 6 / 100 == 0. Use this:

float taxedvalue = (6.0f / 100.0f) * cartTotal;

Note: this will also work:

float taxedvalue = cartTotal * 6 / 100;

because the compiler recognizes the first parameter as a float and automatically treats the two integer values as floats when it multiplies and divides.
