How to dynamically assign an order value to a Google Ads conversion tracking script

[Steve75]

I have the Google Analytics WHMCS app installed and configured.

I see there is no Google Ads WHMCS app, haha.

Google Ads has given me the following code to track conversions on my WHMCS site.

<script>
  gtag('event', 'conversion', {
      'send_to': 'AW-xxx/xxx',
      'value': 10.0,
      'currency': 'AUD',
      'transaction_id': ''
  });
</script>

During the Google Ads conversion setup, they asked for a default conversion value which I set to AU$10.

How do I dynamically set the value assigned to the Google Ads conversion based on the order that has just been made in on the order complete page?

The solution was to use 

{$amount}

a WHMCS template variable, for the value. It gets replaced with the amount before the page is sent to their browser:

<script>
  gtag('event', 'conversion', {
      'send_to': 'AW-xxx/xxx',
      'value': {$amount},
      'currency': 'AUD',
      'transaction_id': ''
  });
</script>
