When I try to pay with paypal, an error message appears

when I try to pay with paypal, an error message appears.

It seems paypal wants me to fill all the Upload Photos elements (I have 5 Upload Photos Elements). I uploaded 2 images, the message says it has 3 errors that correspond to the Upload Photo elements that are empty, with no images.

I kindly ask for your advice.

Hello,

You can update the File Upload field and disable the Required feature so you can submit the form properly if the File Upload field is blank.

Here's a guide that you can check and follow: https://www.jotform.com/help/546-how-to-set-a-field-as-required-or-non-required/
