Instead, download the free "Easy PayPal Integration" from http://webprosonly.com.
It also comes with a "Paypal simulator" that allows you to check your code before performing real money transfers.
You can then have a small file that does all you need.
I need a link for people to pay for what they ask me to do for them, but I can't find a way to make a link since the new website layout was made on PayPal; I can't use a button, unless someone teaches me how to use it an e-mail, which would be greatly appreciated either way. Thanks
