Hi There,
I have a issue to find out.
I use the coupon add-on from Gravity Forms. This works fine, but i need the calculation on the subtotal field, not on the total field.
I use a coupon from 5% procent discount. I need that calculation on the subtotal, because i have a deposit calculation after the subtotal field.
I hope someone can helpt me with this issue.
The Coupon Add-On can only apply the discount to the form total, so you will need to use another approach.
You can add a standard text field for the coupon field, then use a calculation field to calculate and show the discount off the subtotal. You will need to also use conditional logic so the discount is only applied when the proper code is entered. To help simplify the calculation of the subtotal and the discount, you can use the Gravity Wiz Subtotal Merge Tag add-on
You might also be able to use the Gravity Wiz eCommerce Fields add-on
