plugoin problem

Hey guys. Im using a plugin for membership control and it does not support my Currency. (South African Rand)

I was told to put this php code in by using pluginception to create a new plugin. I did it but have no idea how thats meant to help add the R currency to the list in the plugins settings?

There should be a way to do simply add the currency in one of the plug ins coding files. Any idea how to find out which one??

Code below

function pw_rcp_add_currency( $currencies ) {
$currencies[‘YOUR_CODE’] = ‘Your currency name’;
return $currencies;
}
add_filter( ‘rcp_currencies’, ‘pw_rcp_add_currency’ );
