Work with one of our develepers and got this to work. Its the imbed code but modified. We wanted it to pull a hidden value from the page and not the URL and this works.
<script src="//app-sj05.marketo.com/js/forms2/js/forms2.js"></script>
<form id="mktoForm_1119"></form>
<script>
MktoForms2.loadForm("//app-sj05.marketo.com",
"851-XTG-642",
1119,
function(form){form.setValues({"ReferrelId":document.getElementById("accountId").value})});
</script>
