PayPal form not working.

I gave you the link to the form you can try the form for yourself and see it it not working.

I can see this thread is related to the following thread: https://www.jotform.com/answers/2267950 

Kindly note that we do recommend to indeed provide as many details about your issue as possible, an image is indeed helpful as sometimes we cannot submit user's form as the payment method is on live status. If possible, please kindly provide the image or more details on the thread listed above, discussing this matter on a single thread will help us to avoid confusion and assist you better. 

Thanks.
