Text at top right of PDF Invoice

Hello,

I've got the following in my invoicepdf.tpl file, and all I've changed are is the size and colour. I'd like to know if there is a status for Overdue that I can use so that when an overdue invoice goes out, the text panel at the top right is red. Happy to add a string to my language override file if need bed.

I can see there are the standard ones for Paid, Cancelled etc, but would like to know if there is one for Overdue?

Look forward to any replies.

# Invoice Status
$statustext = $_LANG['invoices'.strtolower($status)];
$pdf->SetFillColor(71,181,232);
$pdf->SetDrawColor(0,129,200);
if ($status=="Paid") {
$pdf->SetFillColor(151,223,74);
$pdf->SetDrawColor(110,192,70);
}elseif ($status=="Cancelled") {
$pdf->SetFillColor(200);
$pdf->SetDrawColor(140);
} elseif ($status=="Refunded") {
$pdf->SetFillColor(131,182,218);
$pdf->SetDrawColor(91,136,182);
} elseif ($status=="Collections") {
$pdf->SetFillColor(3,3,2);
$pdf->SetDrawColor(127);
}
