Hello:
 Buy a service that is different in price in Lite or Full   version. The user must be able to choose one or the other version.  which might solve this by using two instances of a module configured with the price for the Full version and set the price of the Lite version.
The problem is that I need to give the buyer the possibility to choose the number of users because this number determines the final price * users Version = Final Price.

As I do this with the module?, Have reviewed the documentation and did not find how.
I hope your help with this

Hello:
Can you suggest a way to calculate the price before and pass it the module code? that is automatic and is not placed in the configuration?
It is important to use the module or not.Thanks
