I'd need to add a Paypal ordering form where it should be possible for customers to choose a service (I am not seling goods) offered in many different options.
Say, for instance, to have displayed:
Service A, and then a field showing a drop down menu with Participants Number 1/2/3...etc for it, with total selling price displayed accordingly with the amount of participants chosen.
Even better if I could display multiple choices both in Service field and Participants field, and then have a total price automatically calculated accordingly with different combination of choices.
Does it exist a plugin offering such features?
