What settings do I use with my $10 off coupon code so people can order multiple seats with $10 off each seat?

I cloned your form Form ID: 50676939973980 and saw that you are using PayPal payment. You can use Coupon Code to give the % discount to members that have the code (if they are qualified, you can give them the Coupon Code initially)

user guide: -How-To-Add-Coupon-Code-in-the-Payment-Form

If I understood correctly you want to achieve following, e.g.:

- You have 3 seats each is 30$ price = total amount 90$

- If coupon is applied you want to give same discount for each seat that is selected

- If discount is 10$ and 3 seats are selected than total should be 60$

Correct? If that is the case you can make logic with percentage inside of your coupon wizard where you will put that your discount is 33.33%.

After applying coupon inside of your form for three seats total amount will look like this:

Hope this will help.
