Why application form did not go through?

I have to go to the incomplete to complete application.   Applicants paid and signed the application.  Why are they in the incomplete group for last 3-5 application?

 

 

If I understood correctly you are receiving incomplete payments.

There are two reasons why the submissions ended up in incomplete payments:

1. The user did not complete the payment in the checkout page, then the submission will go to the Incomplete Payments. Please take note that completing it will not process any payments.

2. IPN of your PayPal account is disabled. When the users completes the payment, a message is sent to JotForm through IPN that the payment was successful. If the IPN of your PayPal account is disabled, JotForm will not know that the payment was successful.

I would suggest you to check your PayPal account and ensure that IPN is enabled.

I went to paypal account, but it ask for "Notification URL". What URL
