Why the embedded form is not accepting credit card details?

Hi, I have had several clients report that they cannot book on to my courses using the jot form page as it will not allow them to enter credit card details.  I've just tried and it did the same to me.  Can you help please?

We are sorry for the inconvenience this may have caused. I was able to replicate the issue on my end, please try to embed the form using the iFrame method: Getting-the-Form-iFrame-Code

Please give it a try and let us know how it goes.
