What's wrong with that code?

[~Shieru No Tamashi~]

Public Class Refresher

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Enabled = True

    End Sub

    Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        WebBrowser1.Navigate("www.gaiaonline.com/profile/friendlist.php")
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Timer1.Enabled = False
    End Sub
End Class

I publish it, click "start" but nothing happens !

EDIT: please help.
