1. Make a copy of Order.php from:




Then added the bold line below around line 1319:

'order' => $this,
'billing' => $this->getBillingAddress(),
'payment_html' => $paymentBlockHtml,
// Adds Grand Total to email
'total' => number_format($this->getGrandTotal(), 2)

The additional line will format the Grand Total to two decimal places. We were working on a single currency store, so we hard coded the currency symbol.

2. Add the ‘total’ variable to your Transactional Email template:

£{{var total}}
