I am a self-taught Dreamweaver mx user who is trying to make a registration page. I am testing this on my local computer which I've installed an asp.net site. My computer is running Win XP PRO.

The page was created by a canned 'insert' page that came with Dreamweaver. The code is below:
<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<%@ Register TagPrefix="MM" Namespace="DreamweaverCtrls" Assembly="DreamweaverCtrls,version=1.0.0.0,publicK eyToken=836f606ede05d46a,culture=neutral" %>
<MM:Insert
runat="server"
CommandText='<%# "INSERT INTO webcontacts (ContactFirstName, ContactLastName, EmailAddress, CompanyName, BillingAddress, City, PostalCode, StateOrProvince, PhoneNumber) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)" %>'
ConnectionString='<%# System.Configuration.ConfigurationSettings.AppSett ings("MM_CONNECTION_STRING_connReg") %>'
DatabaseType='<%# System.Configuration.ConfigurationSettings.AppSett ings("MM_CONNECTION_DATABASETYPE_connReg") %>'
Expression='<%# Request.Form("MM_insert") = "form1" %>'
CreateDataSet="false"
Debug="true"
>
<Parameters>
<Parameter Name="@ContactFirstName" Value='<%# IIf((Request.Form("ContactFirstName") <> Nothing), Request.Form("ContactFirstName"), "") %>' Type="WChar" />
<Parameter Name="@ContactLastName" Value='<%# IIf((Request.Form("ContactLastName") <> Nothing), Request.Form("ContactLastName"), "") %>' Type="WChar" />
<Parameter Name="@EmailAddress" Value='<%# IIf((Request.Form("EmailAddress") <> Nothing), Request.Form("EmailAddress"), "") %>' Type="WChar" />
<Parameter Name="@CompanyName" Value='<%# IIf((Request.Form("CompanyName") <> Nothing), Request.Form("CompanyName"), "") %>' Type="WChar" />
<Parameter Name="@BillingAddress" Value='<%# IIf((Request.Form("BillingAddress") <> Nothing), Request.Form("BillingAddress"), "") %>' Type="WChar" />
<Parameter Name="@City" Value='<%# IIf((Request.Form("City") <> Nothing), Request.Form("City"), "") %>' Type="WChar" />
<Parameter Name="@PostalCode" Value='<%# IIf((Request.Form("PostalCode") <> Nothing), Request.Form("PostalCode"), "") %>' Type="WChar" />
<Parameter Name="@StateOrProvince" Value='<%# IIf((Request.Form("StateOrProvince") <> Nothing), Request.Form("StateOrProvince"), "") %>' Type="WChar" />
<Parameter Name="@PhoneNumber" Value='<%# IIf((Request.Form("PhoneNumber") <> Nothing), Request.Form("PhoneNumber"), "") %>' Type="WChar" />
</Parameters>
</MM:Insert>
