Great addon
I want to make an addition; all my prices are inclusive of sales tax (VAT). Somewhere on the invoice I want to show the total of the sales tax as a single item.
This is just a simple mathematical calculation on the total Amount on the invoice. I can do this myself but so far as I see the calculation of the total Amount does not populate a variable that I could call and play with.
I attach a copy of the code below but I do not know enough about this coding to add something like populate a variable, for example, $Amount.
I checked around the various addons available but I did not find anything suitable
Help appreciated


<td align="right" class="'. str_replace('_', '-', $order->totals[$i]['class']) . '-Amount">' . $order->totals[$i]['text'] . '</td>' . "\n" .
