HubSpot uses a cookie called hubspotutk to track users. To enable cookie tracking on your FormCrafts forms, you have to modify the form embed code.

Our original form embed code looks like this:

<script type='text/javascript'>var _fo=_fo?_fo:[];
_fo.push({'c':'nigoc','i':'formid','m':0,'s':0,'w':504}); if (typeof fce=='undefined') {var s=document.createElement('script'); s.type='text/javascript';
s.async=true; s.src='https://formcrafts.com/js/fc.js'; document.body.appendChild(s);fce=1;}</script>
<div id='nigoc' style='height:838px'></div>

To enable cookie tracking add the text in bold to your embed code:

<script type='text/javascript'>var _fo=_fo?_fo:[];
_fo.push({'c':'nigoc','i':'formid'+'?hubspotutk='+document.cookie.replace(/(?:(?:^|.*;\s*)hubspotutk\s*\=\s*([^;]*).*$)|^.*$/, "$1"),'m':0,'s':0,'w':504}); if (typeof fce=='undefined') {var s=document.createElement('script');s.type='text/javascript'; s.async=true; s.src='https://formcrafts.com/js/fc.js'; document.body.appendChild(s);fce=1;}</script>
<div id='nigoc' style='height:838px'></div>

Note that formid in the above examples would be the actual ID of your form.
