How to add UTM forwarded javascript to Marketo embedded form script?

[Jina_Watson]

I'm not someone that uses Javascript. For the instructions of inserting this code into the Marketo embedded form code, how does it drop in exactly?

Like this:

<script src="//app-lon07.marketo.com/js/forms2/js/forms2.min.js"></script>
<script>(function(opts){
  var current = {
        state : document.location.href,
        query : document.location.search.substring(1),
        time : new Date().getTime()
      },
      storage = {
        area : window.localStorage,
        key : 'last_utm_query'
      },
      restored, 
      updated = {};

  if (/(^|&)utm_/.test(current.query)) {
    storage.area[storage.key] = JSON.stringify({ time:current.time, query:current.query });
  } else if (restored = JSON.parse(storage.area[storage.key] || '""')) {    
    if ( window.MktoForms2 && ( current.time - restored.time <= opts.expireDays * 864E5 ) ) {
      updated.state = document.createElement('a');
      updated.state.href = current.state;
      updated.state.search += (updated.state.search ? '&' : '') + restored.query + '&restored=' + restored.time;
      history.replaceState('', {}, updated.state);
    }
  }
})({
  expireDays : 30
});</script>
<form id="mktoForm_1043"></form>
<script>MktoForms2.loadForm("//app-lon07.marketo.com", "041-BQO-927", 1043);</script>

Or like this:

<script src="//app-lon07.marketo.com/js/forms2/js/forms2.min.js">(function(opts){
  var current = {
        state : document.location.href,
        query : document.location.search.substring(1),
        time : new Date().getTime()
      },
      storage = {
        area : window.localStorage,
        key : 'last_utm_query'
      },
      restored, 
      updated = {};

  if (/(^|&)utm_/.test(current.query)) {
    storage.area[storage.key] = JSON.stringify({ time:current.time, query:current.query });
  } else if (restored = JSON.parse(storage.area[storage.key] || '""')) {    
    if ( window.MktoForms2 && ( current.time - restored.time <= opts.expireDays * 864E5 ) ) {
      updated.state = document.createElement('a');
      updated.state.href = current.state;
      updated.state.search += (updated.state.search ? '&' : '') + restored.query + '&restored=' + restored.time;
      history.replaceState('', {}, updated.state);
    }
  }
})({
  expireDays : 30
});</script>
<form id="mktoForm_1043"></form>
<script>(function(opts){
  var current = {
        state : document.location.href,
        query : document.location.search.substring(1),
        time : new Date().getTime()
      },
      storage = {
        area : window.localStorage,
        key : 'last_utm_query'
      },
      restored, 
      updated = {};

  if (/(^|&)utm_/.test(current.query)) {
    storage.area[storage.key] = JSON.stringify({ time:current.time, query:current.query });
  } else if (restored = JSON.parse(storage.area[storage.key] || '""')) {    
    if ( window.MktoForms2 && ( current.time - restored.time <= opts.expireDays * 864E5 ) ) {
      updated.state = document.createElement('a');
      updated.state.href = current.state;
      updated.state.search += (updated.state.search ? '&' : '') + restored.query + '&restored=' + restored.time;
      history.replaceState('', {}, updated.state);
    }
  }
})({
  expireDays : 30
});
MktoForms2.loadForm("//app-lon07.marketo.com", "041-BQO-927", 1043);</script>

Or some other way I'm not interpreting?
