an External form script is messing with my theme menus

Hi,
I have a form on the page that uses a script from emailmeform.com to display the form.
The call to the script looks like this <script src="http://www.emailmeform.com/builder/forms/jsform/K0BO6uRvr86dtcf7ff" type="text/javascript"></script>
The pages are:
http://www.wheeliekeg.com.au/contact/
and
http://www.wheeliekeg.com.au/order-now/

The all menus then display WITHOUT hovering over them?

Any Ideas?
Thanks....
