Multiple forms in a page triggers "Submission failed. Please try again later" message

[Jin_Nakao]

I'm having issues with implementing lightbox onto a page where another embedded Marketo form is placed.

Basically it is same as https://nation.marketo.com/t5/Product-Discussions/Issues-submitting-embedded-Marketo-forms-on-websit....

The thing is that the lightbox is intended to be added over existing pages where I can't change the embedded form code.

The page is outside of Marketo LP.

The error only seems to happen when another form is present so I suspect the multiple forms are the cause of the error message.

Since I tried various things over 8 hours and the original page does not exist anymore but if there are solutions to avoid this, would you share?

Some references I've looked at:

https://nation.marketo.com/t5/Product-Discussions/Multiple-Forms-on-a-Page-Weird-behavior-when-some-...

https://nation.marketo.com/t5/Product-Discussions/How-to-use-same-form-on-page-twice-in-lightbox-and...

Also, I thought about iframe which basically physically separates two forms but treating on submission behavior is troublesome (as I only vaguely understand js and there is no one else to support me) and it is not good for SEO anyway.

The original lightbox script is as below;

<script src="https://app-sjg.marketo.com/js/forms2/js/forms2.min.js"></script>
<form id="mktoForm_99999"></form>
<script>
var done;
function loadLightBoxOnce (func) {
if(!done) {
done=true;
MktoForms2.loadForm("https://app-sjg.marketo.com", "999-ABC-999", 99999, function (form){
var lightbox = MktoForms2.lightbox(form).show();
form.onSuccess(function(){
lightbox.hide();
return false;
});
});
}
}

setTimeout(loadLightBoxOnce,6000);
</script>

Load all forms from the same domain. You probably have one form loading from your LP domain and the other loading from app-*.marketo.com.

Sanford,

  Thank you very much. I would have never thought that would could be the cause of the behaviour.

  And yes, it seems that original embedded form + lightbox type multiple forms in a page is working!!

  Surprised that the issue could be solved that simple.

  Could not thank you much enough.
