Altering the price of a subscription

Our subscription is for a club membership but I would like to add the option to additionally purchase a season pass to events.  I can add the custom field but if they opt for the pass can I calculate the price (membership cost + season pass cost) and send that figure to Paypal so they have only one payment to make?

Thank you for your good work.

Yes of course. You should be able to handle it using Custom Fee Fields feature in the extension, see docs.joomdonation.com/membershippro/basi...ds/custom-fee-fields

Please read documentation, try to setup it and let us know if you have any questions

Regards,
