code I am trying to add is

function custom_script_name(){
?>
<script>(function(w,d,t,r,u){var f,n,i;w[u]=w[u]||[],f=function(){var o={ti:”5038044″};o.q=w[u],w[u]=new UET(o),w[u].push(“pageLoad”)},n=d.createElement(t),n.src=r,n.async=1,n.onload=n.onreadystatechange=function(){var s=this.readyState;s&&s!==”loaded”&&s!==”complete”||(f(),n.onload=n.onreadystatechange=null)},i=d.getElementsByTagName(t)[0],i.parentNode.insertBefore(n,i)})(window,document,”script”,”//bat.bing.com/bat.js”,”uetq”);</script><noscript></noscript>
<?php
}
add_action(‘wp_head’, ‘Bing’);

function custom_script_name(){
?>
<script type=”text/javascript”>
adroll_adv_id = “2JXDUP7BRZDE7D26B7C32Y”;
adroll_pix_id = “23OQFE4GSRCZHKT7WTPNHL”;
/* OPTIONAL: provide email to improve user identification */
/* adroll_email = ” (Email address hidden if logged out) “; */
(function () {
var _onload = function(){
if (document.readyState && !/loaded|complete/.test(document.readyState)){setTimeout(_onload, 10);return}
if (!window.__adroll_loaded){__adroll_loaded=true;setTimeout(_onload, 50);return}
var scr = document.createElement(“script”);
var host = ((“https:” == document.location.protocol) ? “https://s.adroll.com&#8221; : “http://a.adroll.com&#8221;);
scr.setAttribute(‘async’, ‘true’);
scr.type = “text/javascript”;
scr.src = host + “/j/roundtrip.js”;
((document.getElementsByTagName(‘head’) || [null])[0] ||
document.getElementsByTagName(‘script’)[0].parentNode).appendChild(scr);
};
if (window.addEventListener) {window.addEventListener(‘load’, _onload, false);}
else {window.attachEvent(‘onload’, _onload)}
}());
</script>
<?php
}
add_action(‘wp_head’, ‘Adroll’);

function custom_script_name(){
?>
<script type=”text/javascript”>
var _paq = _paq || [];
_paq.push([“trackPageView”]);
_paq.push([“enableLinkTracking”]);
(function () {
var u=((“https:” == document.location.protocol) ? “https” : “http”) + “://www.tag4arm.com/tags4arm/”;
_paq.push([“setTrackerUrl”, u + “tag4arm.php”]);
_paq.push([“setSiteId”, “33”]);
var d = document, g = d.createElement(“script”), s = d.getElementsByTagName(“script”)[0]; g.type = “text/javascript”;

})();
</script>
<?php
}
add_action(‘wp_head’, ‘Tag4Arm’);

it does accept this but still DOESN”T ADD ANYTHING TO THE HEAD

var scr = document.createElement(“script”);
var host = ((“https:” == document.location.protocol) ? “https://s.adroll.com&#8221; : “http://a.adroll.com&#8221;);
scr.setAttribute(‘async’, ‘true’);
scr.type = “text/javascript”;
scr.src = host + “/j/roundtrip.js”;
((document.getElementsByTagName(‘head’) || [null])[0] ||
document.getElementsByTagName(‘script’)[0].parentNode).appendChild(scr);
};
if (window.addEventListener) {window.addEventListener(‘load’, _onload, false);}
else {window.attachEvent(‘onload’, _onload)}
}());
</script>
<?php
}
add_action(‘wp_head’, ‘analyise’);

so I added this and still nothing it saves it but the scripts are not in the pages
