Java script form embed stopped displaying

I have a form that was embedded on my site in an HTML embed window.  The form is javascript and has worked fine until recently where it stopped displaying.  The form provider is said the following:  "

I checked your site and was able to replicate the issue you are experiencing with the embedded form not displaying properly. The likely reason is the type of element you are using to embed your form on your website. It seems you are using an HTML element to embed the form, but the code you are using is a JavaScript embed code.

JavaScript embed codes require an element that supports JavaScript execution, which might not be the case with a simple HTML element in your site builder. This mismatch can cause the form to appear blank or not load correctly.

Could you check if your site builder offers a different type of embed element or widget that supports JavaScript? If so, try embedding the JavaScript code there instead."

Below is the page with the form.  Can someone help?
