title: Opencart Paypal unsupported currency
body: <p>Im trying to support the checkout of ZAR (South African Rand).</p>
  
  <p>So far i have enabled $, this enables the paypal module however the conversion isn't being completed.</p>
  
  <p>The site simply checkout to the value. Eg: R1500.00 = $1500.00 when checking out through paypal.</p>
  
  <p>What is the correct way to do the currency conversion using the built in convertor? </p>
