Currency Converter

So I am having a huge problem copying a currency converter code to my website, it always comes out incomplete/blank. Any words of advice or encouragement will be great, below I have included one of the codes I would like to use:

<!-- EXCHANGERATES.ORG.UK EXCHANGE RATE CONVERTER START -->
<script type="text/javascript">
var dcf = 'ZAR';
var dct = 'BRL';
var mc = '2D6AB4';
var mbg = 'FFFFFF';
var f = 'arial';
var fs = '11';
var fc = '000000';
var tf = 'arial';
var ts = '14';
var tc = 'FFFFFF';
var tz = 'userset';

</script>
<script type="text/javascript" src="http://www.currency.me.uk/remote/ER-ERC-1.php"></script>
<small>Source: <a href="http://www.exchangerates.org.uk" target="_new">ExchangeRates.org.uk</a></small>
<!-- EXCHANGERATES.ORG.UK  EXCHANGE RATE CONVERTER END -->
