FirstURL and FirstReferrer cookie values not being captured by Marketo form

Hi there,


We have a Marketo form embedded on our demo page that has some additional customized code in it. We've been running into an issue where cookie values are only being captured ~60% of the time and believe our code might be the culprit here.


Would love a second opinion here and hear if anyone else has encountered this issue before.


Here's the page and form in question and below is the script that sets one of the cookie values through Google Tag Manager, with the trigger to fire on all pages on DOM.





<script type="text/javascript">
function getCookie(name) {
   var dc = document.cookie;
   var prefix = name + "=";
   var begin = dc.indexOf("; " + prefix);
   if (begin == -1) {
       begin = dc.indexOf(prefix);
       if (begin != 0) return null;
       begin += 2;
       var end = document.cookie.indexOf(";", begin);
       if (end == -1) {
       end = dc.length;
   // because unescape has been deprecated, replaced with decodeURI
   //return unescape(dc.substring(begin + prefix.length, end));
   return decodeURI(dc.substring(begin + prefix.length, end));
function setCookie(name, value, days){
   var date = new Date();
   date.setTime(date.getTime() + (days*24*60*60*1000));
   var expires = "; expires=" + date.toGMTString();
   document.cookie = name + "=" + value + expires + ";path=/;";
if (getCookie('FirstReferrer') == null) {
