    You have to make sure that you have enabled PayPal express in your Paypal account, please review this guide: http://www.jotform.com/help/285-Configuring-PayPal-Express-Integration.

    The security error also means that the information you provide in the Payment configuration is not correct, please make sure to input the correct API details, also review this guide: http://www.jotform.com/help/284-How-to-Obtain-PayPal-API-Credentials.

    Copy the whole API details in your Paypal account and paste it in your text editor such as Notepad then Copy/Paste it from there in the configuration window.
