body: <p>I want to pull a specific value which is 'totalPrice' and setup a variable on GTM. However, I couldn't manage to pull that value yet.</p>
  <pre><code>when I use document.querySelector('.flashMeta') on the browser console I manage to see all the data below
  </code></pre>
  <p>document.querySelector('.flashMeta');</p>
