Ive been learning about this off and on for 24 hours, and finally used some scripts I found and wrote my own. Problem is, when I click subscribe, it takes me to paypal.com but shows me the message "Sorry — your last action could not be completed".

Im hoping someone can spot what im doing wrong because I really need to finish this up.
