Sweet thanks!
I was going through all of the trouble of replicating the mobi-asin manually. I had seen the source and noticed it could use the amazon identifier, but I thought that if I myself manually added the mobi-asin identifier, I could avoid having to use Quality Check, hence the S&R above. Seeing as how that's not possible though, I guess I'll just remove that column and identifier, and let Quality Check do it. Less work that way.
