HI all,
 
Client is having problem with stolen credit cards being checked via his payment gateway.  He sees a lot of $1 transactions going through.  The form is for collecting donations and has a radio button field with: $25, $50, $100, $250, $500 and Other.  Its the other field that is used to enter a $1 payment.
I've tried creating a $1 field, hiding it then setting the Stripe filter to "> $1" but it doesn't stop the payment going through.
Any thoughts?
 
Thanks,
John.
