无法使用tampermonkey脚本

So at first I was trying to make this script to make evony accounts by using xampp but instead now im trying to use tampermonkey but I cant seem to get any of it to work for some reason :/

// ==UserScript==
// @name     Evony account maker
// @include  http://www.user.evony.com/index.do?PageModule=ForgetPassword
// @grant    GM_addStyle
// ==/UserScript==
window.location = "http://www.user.evony.com/index.do?PageModule=ForgetPassword";
var email = rpplaysevony;
var password = daxter23;
var accnumber = 0;
function createaccount(){   
document.getElementById("tab2").click()//trying to click a button with 
// the id of tab2
document.getElementById('username').value = email + accnumber + "@yahoo.com";
}
window.onload = function () { createaccount() }

Any help would be awesome :) also tried

// ==UserScript==
// @name     Evony account maker
// @include  http://www.user.evony.com/index.do?PageModule=ForgetPassword
// @grant    GM_addStyle
// ==/UserScript==
window.location = "http://www.user.evony.com/index.do? PageModule=ForgetPassword";
    //var email = rpplaysevony;
    //var password = daxter23;
    //var accnumber = 0;
    function createaccount(){   
    document.getElementById("tab2").click();
   // document.getElementById('username').value = email + accnumber + "@yahoo.com";
    }
    window.onload = function () { createaccount();}

you've set the script to run on

http://www.user.evony.com/index.do?PageModule=ForgetPassword

your first line changes the page to

http://www.user.evony.com/index.doPageModule=ForgetPassword

the script wont run on'

http://www.user.evony.com/index.doPageModule=ForgetPassword

Hope that helps

OK - so that was a typo

where is the value of 'email' set?

edit 2 -

You have the following:

var email = rpplaysevony;
var password = daxter23;

Are rpplaysevony and daxter23 supposed to be strings or do they refer to some vars you're not showing?

// ==UserScript==
// @name     Evony account maker
// @include  http://user.evony.com/index.do?PageModule=ForgetPassword
// @grant    none
// ==/UserScript==

document.getElementById('username').value = 'rpplaysevony0@yahoo.com';
document.getElementById('pwd').value = 'daxter23';
document.getElementById('pwd2').value = 'daxter23';
document.getElementsByClassName('btn')[0].firstChild.click();
