Trying to figure out what isn't working with my script I've recently ( TRIED ) creating.

( Im making a script for a game called diep.io ) So I've tried loading Jquery and then, under it making the actual script itself. Apparently there is something that tampermonkey does not like about this, what am I doing wrong? :

// ==UserScript==
// @name         Machine Gun --> Destroyer
// @version      1.0
// @description  This will make you automatically switch to destroyer when pressing "R" ( Useful for sandbox or betraying teamers )
// @author       S O-P
// @match        https://www.reddit.com/r/diepio_scripts/
// @include  http://diep.io/*
// @connect  diep.io
// @namespace  N/A
// @require http://code.jquery.com/jquery-latest.js
// ==/UserScript==
function addJQuery(callback) {
    var script = document.createElement("script");
    script.setAttribute("src", "//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js");
    script.addEventListener('load', function() {
        var script = document.createElement("script");
        script.textContent = "window.jQ=jQuery.noConflict(true);(" + callback.toString() + ")();";
        document.body.appendChild(script);
    }, false);
    document.body.appendChild(script);
}
function main(){
    $(document).ready(function()
                      {
                          setTimeout(function(){
                              /*$('.fluid_types').val('Liquid');
                              $('.fluid_types').triggerHandler('change');
                              setTimeout(function(){
                                  $('.fluids').val('Ammonia');
                              },500);*/

                          },2000);
                      });

// load jQuery and execute the main function
