var adpushup = window.adpushup || {};
adpushup.que = adpushup.que || [];
adpushup.que.push(function () {
if (adpushup.config.platform === "MOBILE") {
adpushup.triggerAd("fdd9bf87-4faf-4493-82b4-e5538b31931a");
} else if ((window.outerWidth <= 768) || (window.outerWidth == 0)) {
adpushup.triggerAd("fdd9bf87-4faf-4493-82b4-e5538b31931a");
}
});
