How can I add an "other amount" box to my payment form?Asked by chsmc on October 21, 2016 at 12:23 PM
I am creating a donation form for the charity I work for. I have included choices of some amounts as options, but I would also like to add an "other amount" box for those who would like to donate their own choice of amount. Can I do this?
So basically it seems to me that you want have a payment form with your choice options and an included additional option to allow an other custom amount, correct?
For something of this sort it might be better to consider making your choices a regular field such as a checkbox option and enable the other field and you can then send that into your payment integration.
You can get a better idea of what I mean by that by referring to the following guide https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field .
