    Do you support custom calculations?

    Asked by Mike on January 30, 2015 at 04:36 PM

    Entry fees are based on number of events the athlete is competing in. If they are in one it is $300, if they are in 2 or more it is $350. Can I link this calculation to their responses for the checkbox field that asks what events they plan on competing in?

    Yes, we can calculate the total amount based on the items selection, and then pass it to the payment field.
