    Asked on March 09, 2018 at 10:16 AM

    I am using this form to collect orders.

    I've had six people able to place orders (including two this morning), but at least a dozen others contact me to say the form doesn't work and they get this error message.

    PCI :: Invalid Data
    This transaction cannot be processed. The amount to be charged is zero.

    Go back and fix
    What do you recommend?  I don't understand how some are placing orders and some cannot.

    I checked your form and got this error on submission:


    This type of error can usually occur because your username, password or signature for your PayPal Pro integration is incorrect.

    When I tried to verify your account I got this error:


    So please check your credentials again.
