I'm receiving the following error in my browser console when I click the "Pay" button of the checkout process:

Uncaught ReferenceError: EJV1_validateForm is not defined
at HTMLButtonElement.onclick (https://www.e-junkie.com/ecom/gb2.php?c=cart&i=38403&cl=4018&ejc=2&o1=S%20(%2420)&o2=Gals&cart_md5=null&cart_id=null&cart_currency=null&to_country=null&zipcode=null#!CCForm:1:1)

This is breaking the form and not allowing transactions to complete successfully.

Could you take a look and let me know? This is happening on your demo page too (https://www.e-junkie.com/wiki/demo/paypal-payments-pro2) - I tested in an incognito tab - so isn't isolated to my site.
