I am using Magento ver. 18.104.22.168 and Payflow Express checkout. I am not able to continue to paypal payment when I use percentage discount coupon.
Its working fine with the fix amount coupon.
Its always showing me following error.
PayPal gateway rejected the request. Field format error: 10431-Item amount is invalid.
I already tried to change the roundPrice decimal to 4 from 2.
Can anyone help me to fix this issue?
