Trigger A/B test in Adobe Target when someone enters Invalid or Expired Coupon

[julie_mry]

We would like to create an A/B test that is triggered by one or two events, 'Coupon Invalid' or 'Coupon Expired', to reward visitors with an instant discount. How can we implement this with Target? 

Many thanks

You can fire activity on coupon code page url and write your actions in custom code under modifications tab.

E.g. by using onclick event you can simply trigger changes depending on your conditions.
