HTML

So basically I have a web browser in a form.
The website displays a login.
I can input values into the username and password boxes just fine.
However when I come to press the login button nothing happens.
If i try this without using code, so i move my mouse onto the webbrowser and try and click the button myself nothing happens.

Website I am trying to log in to : "[url to hacking tool removed]"

#The URL that was removed is a DDOS tool. I use this because I own multiple domains so I like to test it.

What I have tried:

Dim allelements As HtmlElementCollection = WebBrowser1.Document.All

For Each webpageelement As HtmlElement In allelements


    If webpageelement.GetAttribute("id") = "logo" Then
        webpageelement.InvokeMember("click")
    End If
