PAyPal business: bad request error

The paypal integration on our form is not working. We are not sure why. This is a form that was copied from another form that our nationals gave us. However, I am not sure why things are going wrong. We tested it before sending out and thought that we got all of our kinks worked out. But now one of our applicants is trying and is unable to get to the payment part. This is a screenshot it has the same bad request as I did when I tried to go through it. I've checked the settings and everything is fine with the Paypal. We have not changed anything on the form since the first person did theirs? Any help would be greatly appreciated.

Hello Jacqueline  - I apologize for the inconvenience.

I did check your form and can see that the PayPal integration is indeed set up correctly. Could you please try the following to troubleshoot?

1. Disconnect PayPal Business integration and integrate again
2. Clear Form cache

Let us know how it goes.
