The code for my aspx signup page does not work - asp.net

Question

Hello the following code for my signup page does not work. when I execute it, it refreshes and stays in the same page. But it is supposed to redirect to a page called message.aspx. The register command works as follows the person trying to register writes in comboboxs their information and then once they finished, they click the button begin which will save all their information and then use it to personalize the message.aspx page and the person will receive an email.
here is the code:
Private Sub cmdRegister_Click(sender As Object, e As System.EventArgs) Handles cmdRegister.Click
Dim status As MembershipCreateStatus
Dim organization As New Org
Dim employee As New Employee
Dim description As New Description(25)
Dim userMembership As MembershipUser
Dim stringBuilder As New StringBuilder
Try
Membership.CreateUser( _
txtUserName.Text, _
txtPassword.Text, _
txtEmail.Text, _
"question", _
"answer", _
True, _
status)
If status.ToString = "Success" Then
organization.GSTRate = 1
organization.QSTRate = 1
organization.AccountStatus = 2
organization.Name = txtOrg.Text
organization.Active = 1
organization.OrgTypeID = cboType.SelectedValue
organization.Create()
organization = Nothing
organization = New Org(txtOrg.Text)
employee.Username = txtUserName.Text
employee.OrgID = organization.ID
employee.FirstName = txtFName.Text
employee.LastName = txtLName.Text
employee.Title = txtTitle.Text
employee.Username = txtUserName.Text
employee.IsAdmin = True
employee.IsSupervisor = True
employee.IsAccountant = False
employee.IsAdvalorem = True
employee.Email = txtEmail.Text
employee.Phone = ""
employee.Create()
Roles.AddUserToRole(employee.Username, "Admin")
userMembership = Membership.GetUser(txtUserName.Text)
stringBuilder.Append(description.EnglishDescription)
stringBuilder.Replace("(name)", employee.FirstName & " " & employee.LastName)
stringBuilder.Replace("(OrgName)", organization.Name)
stringBuilder.Replace("(username)", employee.Username)
stringBuilder.Replace("you must activate your account", "you must <a href='https://www.advataxes.ca/login.aspx?action=activate&id=" + userMembership.ProviderUserKey.ToString + "&username=" + userMembership.UserName + "'>activate your account</a>")
SendEmail(userMembership.Email, "Advataxes: Account created ", stringBuilder.ToString, Session("language"))
Session("NewUserEmail") = userMembership.Email
Response.Redirect("message.aspx?id=364")
Else
lblInvalidUserName.Visible = True
If status.ToString = "DuplicateUserName" Then lblInvalidUserName.Text = "Username already exists"
End If
Catch ex As MembershipCreateUserException
MsgBox(GetErrorMessage(ex.StatusCode))
Catch ex As HttpException
MsgBox(ex.Message)
Finally
userMembership = Nothing
organization = Nothing
employee = Nothing
description = Nothing
End Try
End Sub

Answer 1

Looking at your code, I suspect the code execution is not successfully reaching the Response.Redirect("message.aspx?id=364") line and due to an exception the flow jumps to catch block/
Two possibilities I can think of:
Exception is thrown inside SendEmail method if smtp is not configured
Membership.CreateUser is failing due to incorrect database connectionstring
I suggest you put a breakpoint inside the cmdRegister_Click method and step through the code.
