Desesperado con document.write

[_Adrian_]

Intenta ponerlo así:

Código Javascript:

function() {
    var hzex = document.createElement("script"); hzex.type = "text/javascript";
    hzex.src = "http://www.heyzap.com/javascripts/embed.external.js";
    document.getElementsByTagName("head")[0].appendChild(hzex);
    var tm = setInterval(function () { if(typeof window["Heyzap"] == "function") {
      (new Heyzap('heyzap_games__65e16a', {"embed_key":"8073aaf2b","width":"1000"})).renderPortal();
      clearInterval(tm);
    }}, 100);
  };
document.write('<div id="heyzap_games__65e16a"></div>');
