Custom Script in Checkout Tracking Code

[Snooxx]

Hi, 

we want to integrate a code like this:

<script src="https://js.adsrvr.org/up_loader.1.1.0.js" type="text/javascript"></script>
<script type="text/javascript">
ttd_dom_ready( function() {
if (typeof TTDUniversalPixelApi === 'function') {
var universalPixelApi = new TTDUniversalPixelApi();
universalPixelApi.init("XXXXXXX", ["YYYYYY"], "https://insight.adsrvr.org/track/up");
}
});
</script>

In the Moment i dont see this Code in the Checkout Process. We integrated in Settings/Checkout/Additional Scripts

What did we wrong?

If you add code in Settings/Checkout/Additional Scripts then it will load on order status page when order successfully complete. 

If you want to load script on checkout (information) page then add in online store->preferences-> add Google Analytics code so you ca see Additional script box->paste your script in this box.
