Problem with itaobuy spreadsheet - need help

I've been tracking itaobuy spreadsheet updates for the past 19 months, and here's what changed: - New interface rolled out about 1 weeks ago - Shipping options expanded to include 11 new carriers - Fee structure changed slightly (actually in our favor) - Response times improved significantly Overall, I'd say the platform is getting better. The spreadsheet functionality specifically has seen 13 updates based on user feedback. For anyone hesitant, I'd say give it a try with a small order first. That's what I did, and now I'm a regular user. Happy to answer questions in the comments.
