RadioButtonList causing email error [Archive]

Hi

I have a simplified example of a form I am trying to create to send user feedback.

It works fine unless the form is submitted without checking a radio button. Since it is not a required field, I can't work out a way around it.

Any help would be much appreciated.

Thanks

<% @Import Namespace="System.Web.Mail" %>
<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="UTF-8" %>

<script runat="server">

Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)

end sub

Sub btnSendFeedback_Click(sender as Object, e as EventArgs)

Dim objMM as New MailMessage()
objMM.To = "mail@address.co.uk"
objMM.From = "myform@address.co.uk"
objMM.BodyFormat = MailFormat.HTML
objMM.Priority = MailPriority.Normal
objMM.Subject = "Test email"
objMM.Body = "You selected " & question1.SelectedItem.Value & ", thanks" & _
"See you soon"

SmtpMail.SmtpServer = "localhost"

SmtpMail.Send(objMM)

response.Redirect("default3.aspx")

End Sub

</script>
