What's the URL of your page?Are you inserting the single form via the Forms 2.0 API, or dragging it onto a FFLP, or are you doing exactly as the OP described?

I'm not exactly clear on why you'd want to submit a form that (in this case, by definition) has no new data. You can accomplish the same tracking (with no wear-and-tear) by appending to the query string of your Thank You URL something like ?from=knownLead.

Hank, this is straightforward if you create a webhook endpoint -- one of the primary ways we use 'hooks is to loop back from one lead to another. Although webhooks are more expressly designed to enhance lead info or post lead info to third-party systems (for fulfillment, say) there's no requirement...

Ah! You must mean the "Forms 2.0 Cookbook" I keep saying I'm going to finish. I can send you the link to my (public) CodePens... anything that starts with MktoForms2 :: is bound for the cookbook. But the only documentation is in code comments.

In fact the Known Lead HTML can be leveraged to forward to the Follow Up URL quite easily.For the Known Lead HTML, type:

Great, glad it worked!

Put this in your Known Lead HTML:EDIT: Use this instead in your Known Lead HTML:Then add Custom CSS to the form:.knownLead .mktoModal { display: none;}

It's pretty easy to do this using the Forms 2.0 API.The real question is how you want the results to be saved to Marketo. For example, a single field that stores Choice1=value1;Choice2=value3;Choice3=value4 is not going to fun to parse in a Smart List. How are you going to action/report on the res...

Well, this doesn't really have anything to do with the form itself. You have a custom "button" (actually an tag) running JS. Unfortunately, because it isn't a real button, there is no built-in way to set it to disabled so it won't respond to the second click. It is quite easy to do with JS, if you are comfortable there: given your developer's current choices (which I don't really agree with) most straightforward is : onclick="this.setAttribute('onclick',''); MktoForms2.loadForm..."I would recommend instead using a real button and styling it to match the current look. The tag is sadly underused IMO.

What's the actual URL of the page hosting the form?
