Clicking Id on page Problem

[mr3army]

Hi,
Im trying to click a button on http://www.threatexpert.com/submit.aspx but my code does not want to fill it in.
It fails are the

Form2.WebBrowser1.Document.GetElementById("txtEmail").SetAttribute("value", TextBox1.Text)

Form2.WebBrowser1.Document.GetElementById("File").InvokeMember("click")
        If Form2.WebBrowser1.Document.GetElementById("File").GetAttribute("value").ToString = vbNullString Then
            Form2.WebBrowser1.Document.GetElementById("File").InvokeMember("click")
            Form2.WebBrowser1.Document.GetElementById("txtEmail").SetAttribute("value", TextBox1.Text)
        Else
            WebBrowser1.Navigate("javascript: WebForm_DoPostBackWithOptions(btnSubmit")

        End If

What is wrong with my code

Cheers

                submitFileSampleToThreatExpert(WebBrowser1, TextBox1.Text) '// Submit File(your WebBrowser used, your TextBox containing the email)
            End If
        End If
