How, can I make a form where a user puts in the name of the file, it works out the price (£0.50 per MB) and they pay via paypal, it checks if the payment has gone through then it automaticly pays every month until they send an email to me saying 'Please cancel blah blah blah.... reasons go here blah blah...'? some help please.
I can do all of that except the paypal bit.
