谷歌分析通用电子商务数据未被记录

我一直试图移动我的谷歌分析电子商务跟踪到通用，但我有一些问题。跟踪本身工作良好，但不是电子商务。我已经启用了电子商务跟踪谷歌分析，并添加了以下代码:

:

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-30033504-40', 'auto',{'name': 'CARATracker'});  // New tracker.
ga('CARATracker.send', 'pageview');

和内部caranew.js

ga('CARATracker.require', 'ec'); 

function CaraGetWidgetDescription(manufacturerWidget) {
    CaraConfig();
     ga('CARATracker.set', 'Widget Impression ID E-tale', String(manufacturerWidget));
}

function CaraAddToBasket(productName, sku) {
    CaraConfig();
    ga('CARATracker.send', 'event', String(productName), 'AddToBasket', String(sku));
}
function CaraBeginTransaction(orderNo, totalPrice) {
CaraConfig();
   ga('CARATracker.ecommerce:addTransaction', String(orderNo), "", CaraPriceFix(String(totalPrice)), "", "0.00", "", "", "");
}
function CaraAddTransactionItem(orderNo, sku, productName, productCategory, productPrice, quantity) {
    CaraConfig();
    ga('CARATracker.ecommerce:addItem', {
        String(orderNo),
        String(sku),
        String(productName),
        String(productCategory),
        CaraPriceFix(String(productPrice)),
        String(quantity)
    });

function CaraEndTransaction() {
    CaraConfig();
    ga('CARATracker.ecommerce:send');  
}
function CaraPriceFix(price) {
    var fixedPrice = price;
    var pLength = price.length;
    var comma = price.indexOf(",") + 1;
    var period = price.indexOf(".") + 1;
    //comma is in the price
    if (comma != 0) {
        //if the comma is not at a 2-decimal point position
        //i.e true for 1,200
        if ((pLength - comma) > 2) {
            fixedPrice = fixedPrice.replace(",", "");
        }
    }
    //period is in the price
    if (period != 0) {
        //if the period is not at a 2-decimal point position
        //i.e true for 1.200
        if ((pLength - period) > 2) {
            fixedPrice = fixedPrice.replace(".", "");
        }
    }
    return fixedPrice;
}

由于这是在一个客户的网站，它是异步与自己的谷歌分析，并设置如下:

<script>  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');  ga('create', 'UA-3521256-1', {'siteSpeedSampleRate': 20});  ga('send', 'pageview');</script><script src="https://where-to-buy.co/scripts/cara/printerlandtest.co.uk.cara.init.js" type="text/javascript"></script><script src="https://where-to-buy.co/scripts/cara/caranew.js" type="text/javascript"></script>

添加到购物篮按钮的代码如下:

<a onclick="TrackEvent('Buy Button Click','ProductList','01327701','');CaraAddToBasket('OKI C511dn','01327701');" id="ctl00_ctl00_ContentPlaceHolderMain_cntPlaceHlderMain_lstCategoryProducts_ctrl0_lnkBuy" class="button product_buy selected" href='javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$ctl00$ContentPlaceHolderMain$cntPlaceHlderMain$lstCategoryProducts$ctrl0$lnkBuy", "", true, "", "", false, true))'><span>Added</span> </a>

然而，我得到以下错误:

Uncaught ReferenceError: CaraAddToBasket is not defined

，当我点击支付，我得到以下错误:

Uncaught ReferenceError: CaraBeginTransaction is not defined

我以为我在函数中定义了它们，但我有错吗?

还有什么可以阻止电子商务跟踪吗?

谢谢
