How do you edit your payment source.

How do you edit your payment source. One of my forms use stripe and i love it, however i am attempting to create another form and will not let me deselect "Purchase Order" as payment so that I may use stripe at that form as well

You cannot deselect the payment field to add another one. You will need to delete the existing Purchase order payment field and then add the Stripe payment field into the form.

Let us know the form URL and we can have a look at that to confirm.
