Hello, I'm trying figure out what the custom code is. Thanks for letting me know


<meta name="msvalidate.01" content="4AED7DB99B0E107628A7001A68E43C71" />
<script type="text/javascript" src="//script.crazyegg.com/pages/scripts/0081/0288.js" async="async"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
// Put our initial page url into a variable       
var initialhref = window.location.href;
// Run the foo function every 1.5s
window.setInterval(foo, 1500);
function foo(){
// Put the current url into a variable
var currenthref = window.location.href;
//If the current url isn't the same as the initial url we need to track a virtual page view
if ( currenthref != initialhref ) {
// The next 2 lines store the folder & page name of the current url in a variable
    var arrsplitvpv =  currenthref.split('http://www.mydomain.com/');
    var trackurl = arrsplitvpv[1];  
// The next looks to see which of the index pages is active and grabs its page title. This code is template specific to the Flatiron template. Other templates will use different selectors. 
    var pagetitle = $("#grid .sqs-dynamic-data-active .project-title h2").text();
// Now push the virtual page view over to Google Analytics  
    _gaq.push(['_trackPageview', '/vpv/' + trackurl, pagetitle ]);
// Finally, reset the initialhref to currenthref so that we can detect any further url changes 
    initialhref = currenthref;
    };      
}
</script>
<script id="mcjs">!function(c,h,i,m,p){m=c.createElement(h),p=c.getElementsByTagName(h)[0],m.async=1,m.src=i,p.parentNode.insertBefore(m,p)}(document,"script","https://chimpstatic.com/mcjs-connected/js/users/8348b8ace6951c3bc03f66e4d/203b96f4e3419477745edb365.js");</script>

It appears to all be custom code.

Is your question what is this custom code doing or what affect does it have on my site?
