Can't click the button, web.

[kimsen]

Hi, i can't find the way to click this button im the webpage.
any ideas?

<td class="dark" onclick="document.getElementById('ga_id').value = '3'; document.getElementById('gaform').submit()">ga videre</td>

I have tried this code, and some other.

Dim allelements As HtmlElementCollection = WebBrowser1.Document.All
'value = "3"

        For Each webpageelement As HtmlElement In allelements

            If webpageelement.GetAttribute("value") = "3" Then

                webpageelement.InvokeMember("click")

            End If
Next
