Hi there. If you go to the following page where I have the form embedded, you can see in the console that there is a javascript error.

Hi, thank you for contacting us.

I have examined the webpage you kindly provided, where your form is embedded, and I would recommend re-embedding the form using the iFrame method.

We have a guide on how to get your form's iFrame embed code here: https://www.jotform.com/help/148-Getting-the-form-iFrame-code

I hope this helps. If you need further assistance please let us know. Thank you.
