无法插入数据！！！

vs2003+sql2000+iis6.0
运行时正常，参数和数据库结构一一对应，但是受影响行数为0.....数据库里没东西T_Tb/s结构代码如下：
web页代码private void ProcessNewAccount()
{
      if(Page.IsValid ==true)
        {
         if(BLL.Customer.addAccount(txtUserName.Text,  txtPassword.Text,txtEmail.Text, txtFirstName.Text, 
txtLastName.Text, txtAddress1.Text, txtAddress2.Text, 
txtCity.Text,listState.SelectedItem.Text,txtPostalCode.Text,
listCountry.SelectedItem.Text, txtTelephoneNumber.Text)==0)
 {
           Response.Redirect("ValidateAccount.aspx?action=errorAccount");
 }
else
{
            HttpCookie customerCookie=new HttpCookie("CustomerId",txtUserName.Text);
   Response .Cookies .Add(customerCookie);
           Response.Redirect("ValidateAccount.aspx?action=createAccount");
}
       }
}bll层代码public static int addAccount(string userid, string password, string email, string firstName, string lastName, string address1, string address2,string city, string state, string zip, string country, string phone)
{
    return DAL.Customer.addAccount(userid,password,email,firstName, lastName,address1,address2,city,state,zip,country, phone);
}
