PDF Serial: Display expiry date

-- HikaShop version -- : 4.4.3
-- HikaSerial version -- : 4.0.0
-- Joomla version -- : 3.10.2

Hi there,

We are using the PDF Serial plugin to create gift vouchers and it is working well.

However, I would like to show an expiry date on the voucher but can't figure out how to add it. In the Coupon Generator, I have set the Discount validity period to 2 years, how do I add the end date to the PDF?

Attached is my PDF set up, to be honest it's just a guess from reading another forum post and needless to say it doesn't work. Can you tell me how to figure out what the boxes should contain?

In a similar way, I would like to add the product description onto a second page of the PDF. Will I be able to do this?

Many thanks
Leila
