Where is Reference Number defined? ($_LANG["invoicerefnum"])

[Keksi]

I need to change Reference Number to KID.

I've done this in the Language files, and now I need to change the numbers being generated.

 

I want the Reference Number to be: (ClientID)(InvoiceNumber)

 

Example:

Client ID: 1567

Invoice number: 3648

ReferenceNumer/KID: 3648

 

 

I know this is easy to do if I just write

<p>KID {$invoiceid}{$userid}</p>

But then I need to remove the Reference Number field. I use the "Offline Payment" option in the billing system, and all the fields defined there is:

Bank Name:

Payee Name:

Sort Code:

Account Number:

 

Not Reference Number witch is directly underneath. Strange..

 

I also need to display the package ID (the unique package number) on the invoice.

 

How can I to this?

 

 

EDIT:

Actually codes like {$total} don't work when adding info to the payment gateway
