Can only use hard-coded rates, not those from openexchangerates

[osuosu]

Really stuck on what to do here as I keep getting the error 'uncaught fx error' whenever I try to get the live rates (hard coding the rates works fine).

Here's the order I'm loading my scripts in:

<script src="jquery.js" type="text/javascript"></script>
<script src="accounting.min.js" type="text/javascript"></script>
<script src="money.min.js" type="text/javascript"></script>
<script src="myscript.js" type="text/javascript"></script>

And here's my jQuery code (myscript.js):

  /* ****************************************************************** */
    /* !CURRENCY CONVERTOR */
  /* ****************************************************************** */   

  // Set up money.js currencies - get latest rates with ajax:  
  $.getJSON(
    'https://openexchangerates.org/api/latest.json?app_id=[my_app_id]',
    function(data) {
      // Check money.js has finished loading:
      if ( typeof fx !== "undefined" && fx.rates ) {
        fx.rates = data.rates;
        fx.base = data.base;
      } else {
        // If not, apply to fxSetup global:
        var fxSetup = {
          rates : data.rates,
          base : data.base
        }
      }
    }
  );

  /*
  // Only hard-coding the rates like below works
  fx.base = "GBP";
  fx.rates = {
    "EUR" : 1.41, // eg. 1 GBP === 1.41 EUR
    "GBP" : 1, // always include the base rate (1:1)
    "SEK" : 13.18,
    "DKK" : 10.55,
    "NOK" : 13.21,
    "USD" : 1.52,
  }
  */

  // Functions to convert prices on collection and product pages
  function osuConvertCurr(priceContainerParent, priceContainer, currencyContainer, activeCurrency) {
    $(priceContainerParent).each(function() {

      var priceToConvert            = $(this).find(priceContainer).data('gbp-price');
      var priceConverted            = fx.convert(priceToConvert, {from: "GBP", to: activeCurrency});
          priceConverted            = accounting.toFixed(priceConverted, 0);

      $(this).find(priceContainer).text(priceConverted + ' ');
      $(this).find(currencyContainer).text(activeCurrency);

    });
  }
  function osuConvertCartItems(currency) {

    // Convert each item
    $('.actual-price').each(function() {

      var itemPrice                 = $(this).text();
      var itemPriceConverted        = fx.convert(itemPrice, {from: "GBP", to: currency});
          itemPriceConverted        = accounting.toFixed(itemPriceConverted, 0);

      $(this).text(itemPriceConverted + ' ');
      $(this).next().text(currency);

    });

  }
  function osuConvertCartCurr(currency) {

    // Convert subtotal
    var subtotal                    = $('.cart-subtotal--price').text();
    var subtotalConverted           = fx.convert(subtotal, {from: "GBP", to: currency});
        subtotalConverted           = accounting.toFixed(subtotalConverted, 0);

    $('.cart-subtotal').find('.cart-subtotal--price').text(subtotalConverted + ' ');
    $('.cart-subtotal').find('.product-currency').text(currency);

  }

  // Set correct dropdown state based on cookie value
  var cc_cookie = $.cookie('_cc_currency');
  if( cc_cookie == 'USD' ) {
    $('.currency-convertor option[value=USD]').prop("selected", "selected");
  } else if(cc_cookie == 'EUR') {
    $('.currency-convertor option[value=EUR]').prop("selected", "selected");
  } else if(cc_cookie == 'SEK') {
    $('.currency-convertor option[value=SEK]').prop("selected", "selected");
  } else if(cc_cookie == 'DKK') {
    $('.currency-convertor option[value=DKK]').prop("selected", "selected");
  } else if(cc_cookie == 'NOK') {
    $('.currency-convertor option[value=NOK]').prop("selected", "selected");
  } else {
    $('.currency-convertor option[value=GBP]').prop("selected", "selected");
  }

  // Set cookie value based on dropdown
  $('.currency-convertor select').on('change', function() {
    var optionValue = $(this).val();
    $.cookie('_cc_currency', optionValue, { expires: 14, path: '/' });
    location.reload();
  });

  // CONVERT CURRENCIES
  // --------------------------------------------------------------------
  if(cc_cookie !== 'GBP') {

    // Collections and single products
    if($('body').hasClass('template-collection') || $('body').hasClass('template-product')) {
      osuConvertCurr('.product-price', '.actual-price', '.product-currency', cc_cookie);
    }

    // Cart page
    if($('body').hasClass('template-cart')) {
      osuConvertCartItems(cc_cookie);
      osuConvertCartCurr(cc_cookie);
      $('.cart-subtotal p').slideDown('medium');
    }

  }

Any ideas of what's going on?

Thanks,
