My zencart sells in MYR currency, however when checkout using paypal express checkout, the currency is converted to USD when charging customer. The fact that PAYPAL has now supporting MYR currency, there should be new option in "Payment > Paypal express checkout > Transaction Currency ( Selected Currency) so that the amount will not be converted to USD. Please let me know how to modify or is there any newer zencart add-ons to support this?:
