When I add a button for PayPal in my shopping cart, the button appears at the end on step 4 which says that the products were purchased and submitted. I want the customers to buy the products, and with this setup they will think the products are free.  My question is:  Is there a way to remove the text on the step 4 page so my customers can click the buy button? Or, is there a way to add the PayPal link to the buy now button on step 3 page where it has the buy now button and the back button with the invoice?
