My paypal button is not working properly. Can you help me?

Whenever I click the submit button on my form this line shows up in the Paypal box:

We are unable to complete your request at this time. Please try again later. We apologize for the inconvenience.

Do I need to contact Paypal for this question?

Thank you,

Amanda
