Quick And Easy Question

[griffithdesign]

I am making an advanced login form but I do not know how to transfer from sub to sub, for example using the fake templates below. How would I make my program go to "ContinueLogin"? As I have tried to explain below.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If Button1.Enabled = True Then
            WebBrowser1.Navigate("http://license.froltentertainment.com/login.html")
            WebBrowser1.Document.GetElementById("username").SetAttribute("value", (TextBox1.Text))
            WebBrowser1.Document.GetElementById("password").SetAttribute("value", (TextBox2.Text))
            Sleep(5000)
        Else
            MsgBox("There was an error connecting to the Frolt Entertainment License System", MsgBoxStyle.Critical)
        End If
    End Sub

Private Sub ContinueLogin(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Sleep(1000)
        If WebBrowser1.Url.Equals("http://license.froltentertainment.com/client/" & TextBox1.Text & ".php") Then
            WebBrowser1.Document.GetElementById("paypal").InnerText.Contains("Valid")
            Form2.Show()
        Else
            WebBrowser1.Document.GetElementById("paypal").InnerText.Contains("Invalid")
            MsgBox("Your current subscription is invalid.", MsgBoxStyle.Critical)
        End If
        MsgBox("There was a problem with verifying your access to this program.", MsgBoxStyle.Critical)
    End Sub
