Base Currency Grand Total is already showing on the payment & review page on checkout with below error.

knockout.js:3381 Uncaught ReferenceError: Unable to process binding "text: function(){return getBaseValue() }"
Message: getBaseValue is not defined
    at text (eval at createBindingsStringEvaluator (knockout.js:2982), <anonymous>:3:57)
    at update (knockout.js:4659)

enter image description here

HTML responsible to show base Currency Grand Total is:



<!-- ko if: isBaseGrandTotalDisplayNeeded() && isDisplayed() -->
<tr class="totals charge" style="border-top: 1px solid;">
    <th class="mark" data-bind="i18n: basicCurrencyMessage" scope="row" style="font-weight: bold;color: #A82682;"></th>
    <td class="amount">
        <span class="price" data-bind="text: getBaseValue(), attr: {'data-th': basicCurrencyMessage}" style="font-weight: bold;color: #A82682;"></span>
<!-- /ko -->

I want to show the same Base Currency Grand Total on Shipping Page, but it is not working.

I have added the same code to this file but it is not showing the base Currency Grand Total.


<span class="mark" data-bind="i18n: basicCurrencyMessage" scope="" style="font-weight: bold;color: #A82682;"></span>
<span class="price" data-bind="text: getBaseValue(), attr: {'data-th': basicCurrencyMessage}" style="font-weight: bold;color: #A82682;"></span>



Note: it is bad practice to update files inside the vendor folder. I will override these files after testing.

It is not enough just to copy the code because there are some checks in KnockoutJs.

The template 'grand-total.html' is called in:


Here you will find the definition of the getBaseValue() function on line 49. You should look for the js file called in the section you want (estimation.html) and add getBaseValue() function.

  • Yes, you are right. It is using in grand-total,html template. I have used in estimation.html template using <!-- ko template:Magento_Tax/checkout/summary/grand-total" --> <span data-bind="text: getBaseValue()"></span> <!-- /ko --> still it is not working
