Stripe integration error: "This field can only contain numeric values"

Hello, yesterday a user reported the following error when attempting to make a donation using our form:  "The site indicated I needed a 'numeric value' for my credit card date.  But it only offered month names." I was able to duplicate the problem (see screengrab) but could not find a way to resolve it. The form was accepting payments as recently as February 19 and we didn't make changes to the form in the meantime. I'd appreciate any insight and/or help you can give. Thanks!

You have a dollar sign in your payment integration as suggested amount:

You should remove it, since only numbers can go through:

Let us know if you have any further questions.

Thank you!
