Hi!
I try to find a way to put the content of a product custom field into the order/invoice-number. It basically contains the zip code of the seller.(not vendor - every product has his own seller). Since the shop is limited to austria the amount of postal codes is limited as well, so I thought I could use the manufacturer variable and make a self defined variable out of the ID od the manufacturer, but the Problem is, that I cannot address this variable, it simply doesn't change anything.

Virtuemart 3.2.14
Joomla 3.8.11

Any help would be highly appreciated
Thanky you very much

edit: In the meanwhile I found some errors in the ordernumber.php: some variables are called $menufacturers but should be called $manufacturers, but still doesn't solve my problem. Unfortunately I am not a developer, so I canot fix this by my own, but as far as I see, I guess the problem is located somewhere between lin 132 and 180. I tried around to set the variable manually but as soon as I put it into an foreach loop it returns null (don't know if that is the correct term for that)
