[RESOLVED] [2005] I have a Cancel button that wants to navigate back

[MMock]

I thought this code would make that happen:

   Protected Sub btnCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnCancel.Click

        ' Dim script As String = "<script>history.go(-1);</script>"
        ' Page.RegisterStartupScript("backupPage", script)


        ClientScript.RegisterClientScriptBlock( _
            Me.GetType, _
            "GoinBack", _
            "<script type='text/JavaScript'>history.go(-1)</script>")
    End Sub

Nothing is happening. I am not going back, there is no javascript error, it just posts back and stays on the same page. Do you see what's wrong? Thanks.
