    I used the information off of paypal but when i did a test with the published form and tried to make a payment it said "Payment Error: Client Authentication failed"

    Not sure what I did wrong

    Thanks in advance for the help.

    That error is usually due to invalid Client ID and/or Client Secret in the payment settings of your PayPal Checkout integration.
