limit to coupon codes?

I have attempted to create a few coupon codes for one of my forms. The entry appears to be accepted but when I return to edit the form again, the additional code(s) are missing. Is there a limit that I'm not aware of?

Hi,

There are no limitations on adding coupon codes.  You should be able to add as many as you want.  After you add a coupon code, make sure to go all the way through to the end of the payment field integration and click "Finish" to save your changes:

If you don't click all the way through, they will not be saved.  Other than that, I just checked to make sure I was able to create as well as save coupons codes and I was without issue.

If you are still unable to have them save after completing your integration after creating the coupons, let us know and we will be happy to have another look.
