Sanford Whiteman I am having a similar issue with prepop on a form that is embedded via html and script on a landing page.
Basically i am trying the below code onto my form that adds an alternate submit button . The lead identification (cookie) seems to work just fine because i see the data going into marketo to the correct lead when the alternate button is pressed. However the form itself doesn't pre-pop with already entered information for the lead. When alternatively i just use the form element directly on the landing page it works just fine on the pre-pop instead of the html code and embed. I also commented out the additional button part of the script and just did a simple form embed code with html and in that case too it doesn't prepop.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<p> <Center>
<button id='MyAlternativeSubmitButtonId'>Save progress</button>
</p>
<script src="//app-ab22.marketo.com/js/forms2/js/forms2.min.js"></script>
<form id="mktoForm_128"></form>
<script>MktoForms2.loadForm("//app-ab22.marketo.com", "876-MVP-978", 128);
//find the button element that you want to attach the event to.
var btn = document.getElementById("MyAlternativeSubmitButtonId");
btn.onclick = function(){
//When the button is clicked, get the form object and submit it.
MktoForms2.whenReady(function (form){
form.submit();
});
};
</script>
</body>
</html>
