I have created an ecommerce site, all is working well. The only issue I have is that when the customer recieves confirmation of payment I get:

PayPal
Confirmed payment with PayPal

and then it also displays a Pay now button, even though the transaction has been completed. 

How can I remove the Pay now button, and just leave the text saying Payment has been completed.

I don't want customers to think they haven't paid, and click on the Pay Now button.

Thanks
