I have to admit that it gets very frustrating that every time I answer your question, the question changes.


When asking questions, the best thing to do is to lay it all out upfront, so the answers, so we know exactly what we are dealing with from the get go, instead of us providing intermediate answers that don't work for you because your question was not complete.

If you like me to continue to try to help with this, I would like to see a small data sampling posting showing all the relevant fields (WBCode, WBCost, WBShipping, ExchangeRate) that covers each situation, and your expected results.
