paypal and sandbox use
I have read the paypal tutorial for using the sandbox. I set up a merchant and buyer account. The directions say to get a buy now button, then copy and paste their code to the button. The button goes on a detail page. The way I have my site set up, is using the add to cart, checkout.php and confirm.php. Do I put their button on my confirm.php page? What about the coding that has my clients account number? My pay pal account is just the plain vanilla premier account.
