Paypal Currency Converter (MAD to EUR ONLY)

Hello there, I want to modify a billing PHP script bought on CodeCanyon (Perfex). I use Moroccan Dirhams (MAD) for invoices but it won't convert automatically to supported Paypal currencies (eg. EUR) when the customer wants to use Paypal Gateway (see attached image). For price consideration : **!!"I only need MAD to EUR support for Paypal"!!** You could use Yahoo API to determine currency exchange rates sent to Paypal The payment library used by billing script for Paypal is Omnipay. For your information, there are plugins that do very well this job but are intended for Woocommerce only. You can have an informational look at : [login to view URL] [login to view URL] Thanks guys
