Not possible to submit PayPal Pro form

Out customers are contacting us, telling us we have several different issues with multiple forms. One problem is, the form will not work using the safari browser when trying to make a purchase using the credit card option. Another problem, customers are saying then they press :pay with visa", nothing happens, there is no drop down that allows the customer to enter his/her credit card info. The third issue, customers are reporting the the submit button does NOTHING. This is my 2nd time contacting you within a week with issues. Please let me know whats going on when this issues can be fixed. We are losing money and customers. 

Thank you for contacting us.

These issues are related to form javascript processing. You can fix this by switching from the Embed code to an iFrame version.

- Getting the Form iFrame Code

I think that a Source Code option should work in your case too.

Please replace the form code with the iFrame/Source version, and let us know if you need any further assistance.
