Script doesn't show up on all pages correctly

[denkadet]

Hello, everybody. It's my first topic as the problem is uncommon. I'm trying to add a script to my website which is on local server yet by using HtmlBox plugin and place the code right into the header so it's supposed to show up on all pages. It actually does show up correctly on the main page but only there.

 

 

On the rest of the pages it goes under the footer as a white area.

 

Can anyone help? The code is a script for callback from zadarma.com looks like 

 

<script type="text/javascript">
var ZCallbackWidgetLinkId = 'my link id is here';
var ZCallbackWidgetDomain = 'my.zadarma.com';
(function(){
var lt = document.createElement('script');
lt.type ='text/javascript';
lt.charset = 'utf-8';
lt.async = true;
lt.src = '' + ZCallbackWidgetDomain + '/callbackWidget/js/main.min.js?unq='+Math.floor(Math.random(0,1000)*1000);
var sc = document.getElementsByTagName('script')[0];
if (sc) sc.parentNode.insertBefore(lt, sc);
else document.documentElement.firstChild.appendChild(lt);
})();
</script>
