• rawamount or price:protected ( code has been attached )

if you're in the invoiceitems foreach loop, then it would simply be...

{$item.rawamount}

• product item quantity number ( default format like this "item Quantity x service name" in $LANG.invoicesdescription )

WHMCS doesn't store product quantities with invoices as a separate field - only if Group Similar Line Items is enabled in general settings -> invoices will the line item description be replaced in viewinvoice as you describe.... if the option is unticked, then each line item will be listed individually.

if you mean SKU type codes, there's no native support for doing this in WHMCS... simplest solution would be to add them to the product names

how can i sum $tax , $total, $subtotal values ?

you surely wouldn't want to sum all three in an invoice, e.g $totals = ($subtotal + $tax + $tax2 - $credit)) ??

it will help you to know that these variables use Price Formatter, which basically allows limited manipulation of them in the template...

so if we go back to your previous question about rawamount, let's say that it equals 100, and your currency is USD (I know it isn't in real life!)

{$item.rawammount} == 100
{$item.amount} == $100 USD
{$item.amount->toPrefixed()} == $100
{$item.amount->toSuffixed()} == 100 USD
{$item.amount->toNumeric()) == 100

the point being that once you have them as numerics, you can add them...

{$subtotal->toNumeric() + $tax->toNumeric() + $tax2->toNumeric()}

this will add the three values together and output them (without any currency prefix/suffix).

it is worth stating that if you're going to do any calculations, and especially for complex calculations, then do them using a PHP action hook and pass the results back to the template.

• and where is discount value ?

if a line item is a discount, then $item.type should equal "GroupDiscount" and it's value would be {$item.amount}... or if you prefer {$item.rawamount}
