I would like the following to appear on our invoices in Zoho Books after the item description:

Qty/ Pack

No Packs

Total Qty

So far, I´ve been able to get them to appear on the invoice:

1. I have added "Qty/Pack" and "No. Packs" in Item preferences.

2. I have changed the label "Qty" to "Total Qty¨in Invoice preferences.

My question is if it is possible for the "Total Qty" to be automatically calculated by multiplying the "Qty/Pack" x "No. Packs"? I know nothing about code or otherwise!

Thanks in advance!
