Do you add this part to the head or body? And obviously, I am guessing you replace the portalId and formId with the forms that I have on my website. Thanks!
jQuery(window).scroll(function() {
if (!jQuery('.hbspt-form').length) {
hbspt.forms.create({
portalId: "PORT_ID",
formId: "YOUR_FORM_ID"
});
}
});
