Inserting data using a Wizard Control ASP.net

Hi there, I am using this code for inserting data from a wizard control. I need to insert data on 2 tables, however I am be able to insert only on first index 0, but when the second part of the wizard is done, the second index is not saving on my other table.
Any help would be appreciated. Thanks.

Partial Class SignUpPhysian
    Inherits System.Web.UI.Page

    

    Protected Sub Wizard1_NextButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.NextButtonClick
        'Dim val(1) As Byte
        If e.CurrentStepIndex = 0 Then
            Dim objEhr As New TarmarikDataContext
            objEhr.Modify_Doctors(1, 1, DoctorName.Text, DoctorLastName.Text, DoctorSurName.Text, DoctorEmail.Text, DoctorOfficeNumber.Text, DoctorMobileNumber.Text,
                                 DoctorFaxNumber.Text, ddDoctorGender.SelectedValue, DoctorAddress.Text, ddDoctorCountry.SelectedValue, ddDoctorCity.SelectedValue, ddCityZone.SelectedValue,
                                 DoctorZipCode.Text, ddDoctorSpeciality.SelectedValue, DoctorLicenseNumber.Text, ddDoctorRUC.Text, DoctorDOB.Text, "BIO")

        ElseIf e.CurrentStepIndex = 1 Then
            Dim objEhr As New TarmarikDataContext
            objEhr.Modify_Users(1, 1, UserId.Text, UserFirstName.Text, UserLastName.Text, DoctorPassword.Text, ddDoctorSecurityQuestion.SelectedValue, DoctorSecurityAnwer.Text, 1, Today, Today, Today, UserId.Text, True, "A")
        End If
    End Sub

    Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
        UserId.Text = DoctorEmail.Text
        UserFirstName.Text = DoctorName.Text
        UserLastName.Text = DoctorLastName.Text
