Your method works great and I am integrating into my cart! Yay!

Since there is no money order option on the payment page when a foreign currency is in the cart, is there an IF statement that can be added to your
PHP Code:
  if ($_SESSION['currency'] == 'USD') { 
        $this->enabled = ((MODULE_PAYMENT_MONEYORDER_STATUS == 'True') ? true : false); 
      } 
to make this note appear:
Please change your currency to USD$ for Check/MO option
I have put this note in 'TEXT_SELECT_PAYMENT_METHOD' but lack the coding knowledge to do an IF statement else { something ,something...'BGP', EUR', echo something...
