Hi Germinal,

Was playing around with the code after installing the latest com_invoices yesterday and found a missing method function in the model since $this->quotes[$i]->subtotal (and total) from the view/tpl was not displaying anything other than 0.
I realized that it wasn't set. I changed model/invoices.php getQuotes() as this:

function getQuotes(){
if (empty( $this->quotes )) {
$query = $this->_buildQuery(2);

$this->quotes = $this->_getList($query, $this->getState('limitstart'), $this->getState('limit'));

for($i = 0; $i < count($this->quotes) ; $i++){
$this->quotes[$i]->subtotal = InvoicesHelper::get_subtotal($this->quotes[$i]->id);

$this->quotes[$i]->total = InvoicesHelper::get_total($this->quotes[$i]);
}
}
return $this->quotes;
}

This fixed the issue.
Can you update the code for next version.

Thanks

Alex
