    I'm sorry for the trouble caused to you.

    I did check your form and I am able to replicate the issue you are having. When the form is submitted and redirected to PayPal checkout page, it displays following error message:


    The issue is caused because of the code you have added in the "Checkout Logo" option of your payPal settings. Please check the screenshot below:


    I deleted the "Checkout Logo" value and that seems to have solved your problem.

    Do test your form and get back to us if the issue persists.

    Thank you!
