Here's my scenario: I'm trying to give a discount to full time members if they were a member while in college. Part of that discount is how many years they were a member while in college. My thinking was, to make a number field be a quantity field with the question "How many years were you a member in college". And that quantity field would point to a price field with the default value of -25.00. But it didn't work. Does anybody know how to apply a discount based on field input?
