I used Auction Wizzard since 2003
I send a several emails since 3/15/2016 nobody replies

I try to list my items on ebay and I got a message
The Auction Lot was not listed. An error was returned by ebay:
APi error Code 21919301: UPS is missing a value . Enter a value and try again.

I even put Does not apply and I got the same message.

I agree....well, not with the part about not using auction wizard, but with the UPC problem. This needs to get looked at. I have many items (about 1 in 10 average on my end) that cannot list until a program update addresses this.

I've been using Auction Wizard 2000 from when it was just Auction Wizard. The Issue with UPC (NOT UPS) is that ebay returns messages that may not actually be because of a missing UPC code, but some other problem. When its merely a UPC that's missing, entering N/A will fix it. However, there are other mandatory fields that can return this error, and that's a ebay issue. I usually get a reply to emails within a day, but I have also had to figure out my errors myself occasionally.
