I miss the decimal point for coupon codes

We have some of our coupon codes set up for 14.3% so that we can give $500 off a course that costs $3497. We offer three payment options, 1) pay in full 2) three payments 3) 12 monthly payments. We use the 14.3% because that makes it $500 off on the pay-in-full option. When I went to update our coupon today, it gave me an error. Now I'll have to come up with a different solution or change the price on my sale because Ontraport won't do that anymore. Please fix this and bring it back.
