Hello. I am making a WoW automatic trial account creator and so far i have it so that on this link:

https://us.battle.net/account/creation/wow/signup/

it will fill out all of the information.

Code:
  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        WebBrowser1.Document.All("firstName").InnerText = txtFirstName.Text
        WebBrowser1.Document.All("lastName").InnerText = txtLastName.Text
        WebBrowser1.Document.All("emailAddress").InnerText = txtEmail.Text
        WebBrowser1.Document.All("emailAddressConfirmation").InnerText = txtEmail.Text
        WebBrowser1.Document.All("password").InnerText = txtPass.Text
        WebBrowser1.Document.All("passwordConfirmation").InnerText = txtPass.Text
        WebBrowser1.Document.All("touAgree").SetAttribute("checked", "true")
       
    End Sub
The only problem I am having is that when I try to make it automatically submit it isnt working because I can't find the id of the button. When I inspect it on the website it is a javascript button and I am not sure how to make it click.

I tried
Code:
 'WebBrowser1.Document.All("Submit").InvokeMember("click")
But it still didn't work. Any help would be much appreciated! Thanks
