NOTES:
<br>
In order to test the code, you must replace the "business" value variable with your PayPal Email Address or Account ID.

Note, you can also use the online button creator to generate the code.
If you want to allow your customers to input an amount on the PayPal Screens for a Buy Now Button, just enter a "0" in the "Amount" Field when you are creating the button. This method works for people who want to use the online button creator. Note, this will "not" work for Add to Cart item buttons.
