Prefill form with different info from different buttons

@Track which dynamic page a new Wix Form was submitted from

Sometimes, you want to know which page a user submitted a form on - which can be especially useful for dynamic pages like a car listing or product detail. This tutorial walks you through how to add that data to your form submission. Setup Step 1: Add a Hidden Field Create a form with a hidden field, for example “Page Submitted” Give it a Field key (Found under the advanced tab). I

Noah, if you’ll indulge me a bit more, I’d appreciate it -

On my ‘weddings’ page, I’ve updated the button link to: http://www.merlotembargo.com/quote?eventType=wedding
(Seems slightly safer to assign a page within wix rather than a URL, but I don’t see a way to attach that eventType parameter if I do it that way.)

I’ve pasted your code onto my quote page, and updated the parameters to match the elements on my page. (I think I’ve got them all, but I’m not a web guy at all, or coder of any sort, so bear with me. Also, it doesn’t work anyway, and as i note below, wix seems to have some issues with my parameters anyway.)

});
$w.onReady(function () {
    $w("#dropdown1").onReady(() => {
        let itemObj = $w("#dropdown1").getCurrentItem();

        let currentPage = itemObj["eventType"];

        $w("#multiStepForm1").setFieldValues({
            page_submitted: currentPage
        });
    });
});

When I hover over the onReady in the second line, wix tells me this property does not exist on type "dropdown. Similar red error message when I hover over getCurrentItem. Do i need to declare these at the top of the code or something,

Please forgive my ignorance!
TIA
