PayPal checkout is not working on my form

I have created a template and form and added a PayPal checkout on the end of the form. Every time someone trys to click on the PayPal link, it shows an error for the user and for myself. Very frustrating

I have just checked the form in your account and noticed it does not have the integration, in order to help you we need to see the issue and perform some tests on our end. 

I would also recommend you to make sure you are integrating your form correctly, here is a guide about it: https://www.jotform.com/help/542-How-to-Integrate-Form-to-PayPal-Checkout
