    you do this through paypal with the options that they offer. when you get your code for your buy now or add to cart they will give you options for both items you asked about. i'm not sure if you have that with the pay pal buttons from the tools. i only used pay pal direct.

      A simple (not very safe with experienced users) way: send them to paypal and set as return page the page where you have the form on.
      To improve security on it: you need to pass over to PayPal a variable (any variable) and get it back through PDT (you need to activate PDT in your PayPal account). In the form page, you need to have another piece of script that will check if PayPal passes back the variable you have set, with the correct value.

      Have a look at http://www.dbtechnosystems.com/payments.php . Basically PayPal buttons are forms. Here i have set the amount and description as variables, you can also set the quantity in the same way (using a field named "quantity" in the PayPal form)
