Hello,
I have built an ASP>net web page with a custom shopping cart. What I would like now is to add a Paypal checkout button that directs the user to Paypal using the grand total from the shopping cart. The user may purchase any number of items plus there will be shipping charges and possibly sales tax as well. Most of the "create button" options I have seen on the Paypal site require a dollar amount. I do not know the amount until the user decides to checkout. Do I use Smart buttons, shopping cart, checkout, something else?
Example: The customer added 6 items to the cart and the grand total is $43.74. I would like to pass the 43.74 to Paypal for processing.
Any help as to where I should start would be helpful
Thank you!
