I have checked the webpage you have shared and I can see you have embedded a JotForm, but it is not showing in the webpage:
What I would suggest you is to embed your form using the iFrame code, this way you will avoid any conflict between the code in your webpage and the code in the form, here's the guide that will help you to get the iFrame code of your form: https://www.jotform.com/help/148-Getting-the-form-iFrame-code
You could also change the height so the form displays completely in your webpage, if after embedding your form using the iFrame code the form still does not work, please let us know.
