Project Description:
It would be best if you have experience in setting up Paypal's Website Payment Pro.

I actually had this set up by another provieder on this website. But when I actually tried it out by using a Credit Card I get this error;

Fatal error: Call to undefined function pphttppost() in /home2/profitfa/public_html/thefifthkey/checkout.php on line 47

I would mainly like bids from people who have set up Paypal's PAYMENT PRO!

Thank you.
