Can I add a coupon code option on regular fields not a payment field?

Hello,

I want to include a referral code/coupon code option in my form. The idea is the following: If a use enters a particular code (from a pre-determined list of codes), he/she will get a %discount on the product price.  However, I'm not using any of the payment fields that you provide by default -> instead its just a simple calculate field (the payment is collected through other models which happen outside the form environment)

Pls. suggest

Thanks

That's possible using contains statement in update/calculate field condition.
