TOPIC: DISCOUNT CODE - Need to discount at end, not beginning

I have a discount code for a user to attend an event free of charge. However, the discount code only works with the initial prices. The problem is that I have a custom field on this event that has to be completed which adds another fee. This fee ends up being the total registration because the discount code is being applied prior to the additional fee. How can I get discount code to be applied after all fees are added?

The discount code, when used, does apply to the final price. Use the "percent" setting (instead of the "amount" setting) when creating the code. Set it to 100%.

The total registration fee, including fees associated with your custom fields, will be discounted to $0.

Thanks Breeze. I do have it set to % but it is only taking the 100% off the initial course fee.
